Effect of Clay Composition and Human Haircut Waste on Mechanical Properties Mechanical Properties of Epoxy Resin Composites

The impact of human haircut waste and the nature of clay soil on the mechanical characteristics of epoxy resin composites has been studied. This study utilizes clay sourced from Wonosari Village, Deli Serdang Regency. The clay was pulverized using a pestle and mortar until it reached a smooth consistency. It is then filtered through a 200 mesh screen and subjected to drying in an oven at a temperature of 105℃ for around 3 h until the water content is completely evaporated. Finally, the dried clay stored in a desiccator. The clay powder was subjected to ball milling for 40 h at 350 rpm. The resulting particle size, determined by particle size analysis (PSA), was found at 0.764 µm. Next, the human haircut waste obtained from the surrounding campus of Universitas Sumatera Utara was prepared by separating the hair from fine hair and washing it clean. Clay soil powder and human hair cut waste are used as fillers, and some variations of epoxy resin mixtures are used. Morphological SEM analysis shows that clay and human haircut waste can be distributed evenly on epoxy resin composites. Testing of water absorption and mechanical properties of the board based on SNI 01-449-2006 standards include the test of dry bending strength (MoR) and the mode of flexural elasticity (MoE) obtained the optimum composition (50: 50: 1: 1) g against the epoxy resin mixture, waste human haircut, and clay soil obtained the water absorption test results of 1.64% with a value of MoE 36789.03 kgf /cm2 and a value of MoR 664,41 kgf/cm2. Test results of mechanical properties and water absorption have fulfilled the SNI 01-449-2006 quality standards for composite boards.

Pemanfaatan Limbah Kertas (Pulp) dan Serat Batang Pisang Menjadi Campuran Bahan Pembuatan Asbes Plafon Ramah Lingkungan

Garbage waste in Indonesia is classified as many, including organic and inorganic. Therefore, research was carried out with the aim of utilizing waste paper and banana tree trunks as a mixture for making environmentally friendly asbestos ceilings. The method used is an experimental method, with a mixture of cement and sand composition of 1:2 namely AP0 (38%, 60%, 2%) ; as well as variations in the composition of the mixture of cement, paper pulp, and banana stem fiber used, among others: AP1 (39%, 60%, 2%) ; AP2 (44%, 55%, 2%) ; AP3 (48%, 50%, 2%) ; AP4 (53%, 45%, 2%) and the various compositions used for mixing cement, paper pulp, banana stem fiber, and sand include: AP5 (39%, 20%, 1%, 40%) ; AP6 (44%, 20%, 1%, 35%) ; AP7 (48%, 20%, 2%, 30%) ; AP8 (53%, 20%, 2%, 25%). The highest average flexural strength results for the variation without sand in the AP4 sample = 68.121 kgf/cm2, while the variation using sand in the AP8 sample = 70.358 kgf/cm2. For the water absorption test results, the lowest average variation without sand was in the AP4 sample = 18.36%, while the variation using sand in the AP8 sample = 12.20%. This test includes flexural strength and water absorption. The use of paper pulp can reduce flexural strength and increase water absorption while banana stem fiber increases flexural strength and decreases water absorption. Therefore, it can be concluded that asbestos ceilings with a mixture of pulp and banana stem fiber are better, economical, and lighter than conventional asbestos ceilings and still meet SNI.

Utilisation of Sandal Waste From Home Industry in Kepuh Kiriman Village, Waru District, Sidoarjo Regency, As Coarse Aggregate Material in Mixing Materials For Paving Block Production

Industrial activity is one of the factors that supports the growth of the economic sector. One industry that is currently proliferating is rubber sandal waste. This paper will use a mixture of rubber sandal waste as a coarse aggregate material. Sandal waste can be reused to produce products with a sale value, such as a mixture for making paving blocks. They were paving blocks that will be made using B-quality K-200. This paper aimed to determine compressive strength, water absorption, and SEM results. The method which is used in this research is descriptive quantitative. Paving Variations in sandal waste used in this study were 0%, 10%, 15%, and 20% of the volume of coarse aggregate. The optimal results produced are a 15% variation with a compressive strength age of 28 days with an average value of 18.8 MPa, a 10% variation with a compressive strength age of 7, and 14 days with an average value of 21.2 MPa and 21.8 MPa. The most optimal water absorption test results are at 10% variation with an average value of 5%. SEM test results with 15% and 20% variations showed a high air void content and microcracks spread in the specimen's topography. Meanwhile, at 0% and 10%, the spread of microcracks is insignificant, and the test object has a reasonably high density.

Water uptake of porous building materials with extremely small air entrapment effects

When a porous material is near capillary saturation, entrapped air is expected to affect water transfer through the pores. Based on the results of water absorption tests at reduced air pressure, Janssen et al. (Energy Procedia, 2015) demonstrated that air entrapment prevents water absorption above capillary saturation. In this study, to understand the air entrapment effects on water transfer in the high-water-saturation region, we further examined the water transfer characteristics corresponding to extremely small air entrapment effects. First, using three common porous building materials, water uptake experiments were conducted at low air pressure near vacuum (several kilopascals), and the time evolution of the water absorption was measured. The results show that low air pressure accelerates water uptake by brick and aerated concrete specimens, whereas the water uptake by calcium silicate board specimens is not significantly affected. These differences among the materials are discussed from the viewpoint of the pore structure. Furthermore, the results of simultaneous water and air transfer calculations confirm that air entrapment and pressure development in the pores can significantly reduce the rate of water uptake and the water content that a material can reach after capillary absorption.

Laboratory investigation on the fracture toughness (Mode I) and durability properties of eco-friendly cement emulsified asphalt mortar (CRTS II) exposed to acid attack

Cement Emulsified Asphalt Mortar (CEAM) has gained prominence as a vital material for its energy and noise damping properties between the concrete roadbed and track slab in a high-speed railway system. Therefore, it is evident that CEAM properties need to be better understood and optimized. Since cracking caused by traffic loading and atmospheric conditions is one of the primary causes of failure in CEAM, addressing this issue is of great importance. Furthermore, there is a growing need for more environmentally friendly and durable CEAM due to the environmental impact of cement production in the form of greenhouse effect. The objective of this study is to assess the impact of partially replacing cement content in CEAM Type II (CRTS II) specimens with pozzolanic materials such as silica fume, metakaolin, and granite sludge to investigate how these pozzolans affect the fracture toughness (Mode I) performance under both normal (water curing) and sulfuric acid exposure conditions with the main focus on evaluating the pozzolans ability to resist acid attack from a fracture toughness perspective as the research novelty. For this purpose, specimens containing pozzolans at 5 %, 10 %, and 15 % substitution level (by weight of cement) were subjected to Semi-Circular Bending (SCB) test both under normal and exposure to 5 % sulfuric acid solution conditions. Moreover, water absorption test was conducted on specimens in normal condition as a durability index. The test results of this study revealed that substitution of these pozzolanic materials enhanced the fracture toughness in normal condition. Specifically, at a 10 % substitution as the optimal level, silica fume and metakaolin resulted in 18 % and 15 % increase in fracture toughness performance compared to the control specimen in normal condition. However, granite sludge exhibited almost the same performance as the control specimen at 5% substitution as its optimal level. In acid exposure condition, the detrimental effect of acid on the fracture toughness performance of specimens was reduced by 61 %, 55 % and 13 % for samples containing silica fume, metakaolin and granite sludge at 15% substitution level, respectively. Furthermore, water absorption test results showed that inclusion of silica fume and metakaolin at a substitution level of 15 % results in 56 % and 47 % reduction in water absorption compared to the control specimen, respectively, while for granite sludge, it was almost the same as control specimen. These results were also confirmed by SEM studies. Since the use of these pozzolans as cement substitution not only improves the fracture toughness in normal condition but also provides protection against acid-induced degradation, this study contributes to the development of a more durable and environmentally friendly CEAM.

Development of a variance model for the prediction of water absorption and thickness swelling for an experimental design pvc reinforced composite pipes

Water absorption is a significant constraint encountered when NFs reinforce polymer matrices. It is the primary cause of the breakdown of the fibre-matrix interface, resulting in swelling of the fibres, loss in the efficiency of load transfer between the matrix and the fibres, and ultimately a reduction in the strength and stiffness of the composites. This study investigated the development of a variance model for predicting water absorption and thickness swelling for an experimental design of Polyvinyl chloride (PVC) reinforced composite pipes. The quadratic model was used to model the influence of the process factors (independent variables) on the responses (i.e., water absorption and thickness swelling). Statistical analysis of the experimental data was carried out by fitting the chosen quadratic model to the data to estimate the unknown model parameters. The results revealed that the model was characterised by a high R2 value, indicating a perfect fit between the experimental observations and model predictions. The value of the variation coefficient was 3.320, which means the high precision and reliability of the model. The results of water absorption tests as a function of independent process factors showed that increasing the level of PVC in the composite material resulted in a decrease in the water absorption capacity of the material. This is desirable since an excellent composite pipe material should resist moisture intrusion.

Evaluation of the water absorption of expanded polystyrene after different periods

This work evaluated the results of water absorption tests on specimens of expanded polystyrene (EPS) in the specific masses of 10, 20 and 30 kg/m³ molded in specimens with cubic dimensions of 100 mm. The tests were carried out according to ASTM C272 (2001). Long-term water absorption tests were also performed, which differs from the simple test by the immersion time of the specimens, in which the test bodies were kept submerged for a period of 28 days, seeking to study the behavior of the EPS when exposed or in contact with water for long periods of time. From the results it was observed that the water absorption parameters tend to decrease with the increase of the specific mass, being that the lower density presents significant water absorption, this shows that there is a loss of the beneficial characteristics of the use of EPS with low density. Thus, it is important to provide a waterproofing system in practice that avoids the direct contact of the geoexpandido with the water, as well as an adequate and efficient drainage system to remove the water in contact with the EPS faster in the construction. It is also worth noting that water absorption represents about 4% of the sample volume and the behavior, both in mass and volume, for immersion in a 24-hour period and 28 days remains similar.

Effect of Wood Dust Fibre Treatments Reinforcement on the Properties of Recycled Polypropylene Composite (r-WoPPC) Filament for Fused Deposition Modelling (FDM).

The efficacy of wood dust fibre treatment on the property of wood dust reinforced recycled polypropylene composite (r-WoPPC) filament was investigated. The wood dust fibre was treated using alkali, silane, and NaOH-silane. The treated wood fibre was incorporated with r-PP using a twin-screw extruder to produce filament. The silane treatment on wood dust fibre enhances interfacial bonding between wood fibre and recycled PP; hence, a filament has the highest wire pull strength, which is 35.2% higher compared to untreated and alkaline-treated wood dust filament. It is because silanol in silane forms a siloxane bond that acts as a coupling agent that improves interfacial bonding between wood dust fibre and recycled PP. The SEM micrograph of the fracture structure reveals that treated silane has strong interfacial bonding between wood dust fibre and recycled PP, having minimal void, gap, and good fibre adhesion. The water absorption test results indicate that filament with treated wood dust absorbs less water than filament with untreated wood because the treatment minimizes the gap between wood fibres and recycled PP. The FTIR analysis identified the presence of silane on the wood dust surface for silane-treated wood dust. The DSC studies suggest that the temperature range 167-170 °C be used in the extrusion machine to produce r-WoPPC filament. As a result, r-WoPPc filaments containing silane-treated wood dust have better mechanical properties and have a greater potential for usage in FDM applications.

The Mechanical Properties of Fly Ash and Slag Geopolymer Mortar with Micro Steel Fibers

In this study, experimental mortar combinations with 1% micro steel fibers, were examined to create geopolymer mortars. To test the effect of the fibers on the mortar's resistance, the geopolymer mortar was designed with various proportions of more environmentally friendly materials fly ash and slag. The percentage of fly ash by weight was 50, 60, and 70% of the slag. The best results were obtained when a 50:50 ratio of fly ash and slag were mixed with 1% micro steel fibers. The results showed that the mixtures containing fibers performed better in the considered tests (toughness index, ductility index, and resilience index). In the impact resistance test, the mixture contained 50% fly ash by weight of the slag with a temperature of 240°C and a curing period of 28 days, with and without micro steel fibers. Water absorption test results and void content increased when adding micro steel fibers after 7 and 28 days of curing at 24°C.

Mechanical and water absorption behaviour on silane treated jute fiber based natural composites

In this study the mechanical behaviour of chemically modified jute fiber based bio composites was discussed. Vacuum infusion process was used to fabricate the natural fiber reinforced composites with three stacking order of jute fibers in the woven form. Four mechanical properties were analyzed using tests like impact, flexural, tensile & shore-D hardness as per ASTM norm. The structural analysis was characterized by scanning electron microscope. The water absorption test specimen was prepared in accordance with ASTM-D570. The obtained experimental result of silane treated jute fiber sample provides better mechanical strengths compared to non-treated sample. The water absorption test results showed that chemical treatment of jute fiber, the polymer matrix strongly bonded with jute fiber, which restricts the water molecules to sneak into the fiber phase.

Effects of solvents on electrospun fibers and the biological application of different hydrophilic electrospun mats

It is reported that low volatile solvent could slow down the rate of solvent volatilization during the electrospinning process and hydrophobic biomaterials were easily to form branching fiber, which would be used as a potential biomaterial as wound dressing because of its bacterial barrier property. In this work, silver ion (Ag+) was used as the anti-bacterial components to explore the effect of N, N-dimethylformamide (DMF) as a fiber differentiation inducer on hydrophilic materials-Polyvinyl alcohol (PVA), Polyvinylpyrrolidone (PVP) and Eudragit L-100 during the electrospinning. The results of scanning electron microscopy (SEM) and X-ray diffraction (XRD) confirmed that DMF could reduce the diameter of electrospun fibers and increased crystallinity of the electrospun fibers. The results of water absorption test, X-ray photoelectron spectroscopy (XPS) and in vitro antibacterial activity showed that comparing with cotton non-woven fabric, gauze and cotton, the fiber with strong water absorption could load more silver ions and had stronger inhibitory properties against Staphylococcus aureus (S. aureus) and Escherichia coli (E. coli). CCK-8 assay showed that the cytotoxicity of DMF induced hydrophilic material electrospun fibers and their silver loaded electrospun fibers were all above 90%, which suggested that the fibers could be developed for clinical application. This work could provide an opportunity for improving the properties of electrospun fibers which have potential to be applied as wound dressings.

Kuat Tekan dan Penyerapan Batako Menggunakan Serat Pelepah Kelapa

Brick is a building material that has a function as a room sealer. Its larger size, when compared to red brick, makes bricks more in demand in the market. Improving the quality of bricks needs to be done to meet the needs of the building. The use of added materials becomes one of the things that can be considered to improve the nature and quality of bricks. This research aims to find out the strong press and absorption of bricks with the use of coconut pellet fiber. The research was conducted experimentally with the manufacture of test objects in the laboratory. The test object used is in the form of a beam of 30x15x10 cm. The percentage variation of coconut fiber is 5%, 10%, and 15% of the weight mass in bricks. The tests carried out include a strong compressive and water absorption test with reference to the Indonesian National Standard (SNI). The results of water absorption tests obtained the optimum value in bricks with a mixture of 5% fiber which is 6% of the mass of the weight of the brick, while the minimum value is in the brick, 15% fiber, which is 10%. While the compressive strength results get the optimum value on the 5% fiber mix variation, which is 20.1 kg/cm², and the minimum value on the variation of 15% fiber is 8.8 kg/cm². From these results showed that bricks with coconut pellet fiber have not been able to improve the quality of bricks.

Compressive Strength Performance of Composite Sand Cement Brick with Power Saw Wood

Malaysia is experiencing an unprecedented growth of its urban centre due to its developing economy and industrialization, causing the demand of bricks production to be high. This increased the price of river sand. Further, the river sand may be depleted in the future if there is no alternative taken in reducing the usage of river sand in building materials due to the limited natural resources supply. Therefore, this research concentrates on using waste material like wood fiber waste (WFW) in order to reduce river sand in the fabrication of composite sand cement brick. This research is done in order to determine the water absorption and the compressive strength of sand cement brick with powder saw wood. Six batches of bricks were made with different composition of sawdust of 0%, 1%, 2%, 3%, 4% and 5% sawdust. All the bricks undergo 7 days of air-cured process before having the water absorption test and compression test. 3 days of water-cured process was performed on all bricks in order to investigate the results of water absorption test. For water absorption test, 0% of sawdust brick shows the lowest value while 5% of sawdust brick shows the highest value of water absorption rate. This indicated that high percentages of sawdust in composite brick will results in higher water absorption rate. This factor is due to the sawdust that is hydrophilic and porous in nature that causes the brick to containe more air space in the brick. Thus, this can be evidenced by the density data that keep decreasing with increasing percentages of sawdust. As for compressive strength test, the results presented 0%, 1%, 2%, 3%, 4% and 5% of sawdust have strength of 20.61 MPa, 25.30 MPa, 15.47 MPa, 2.03 MPa, 1.49 MPa and 1.73 MPa respectively. In summary, it can be concluded that optimum percentage of sawdust is 2% as it contains better compressive strength than other bricks although it has slightly higher water absorption rate than conventional sand cement brick. The compressive strength was influenced by the density of brick. It is shown in density results that decreasing in density will causes declining in compressive strength. As a conclusion, water absorption rate increases linearly proportional to the percentages of sawdust but inversely proportional to the compressive strength and the density of the brick.

The effects of melt grafted maleated polybutylene succinate on the properties of poly(hydroxybutyrate‐co‐hydroxyhexanoate)/polybutylene succinate blends

AbstractPoly(hydroxybutyrate‐co‐hydroxyhexanoate) (PHBHH)/poly(butylene succinate) (PBS) blends were prepared using a melt blending technique. A compatibilizer of maleated PBS (PBSgMA) was produced using reactive melt grafting by varying the maleic anhydride (MA) monomer concentration ranging from 3 to 10 parts per hundred resin (phr). Fourier‐transform infrared (FTIR) spectroscopy and nuclear magnetic resonance (NMR) spectroscopy analyses confirmed the grafting reaction of the PBSgMA. The PBSgMA was incorporated in the 80PHBHH/20PBS and 50PHBHH/50PBS blends to investigate the effect of maleated compatibilizer on the tensile, flexural, drop weight impact, and water absorption properties of the blends with droplets dispersed and co‐continuous morphology. The incorporation of PBSgMA increased the tensile and flexural strength of both the 80PHBHH/20PBS and 50PHBHH/50PBS blends, where the optimum properties achieved at 5 phr concentration of MA. The drop weight impact test results showed that uncompatibilized and compatibilized 50PHBHH/50PBS blends had higher critical strain energy release rate (Gc) than the neat PHBHH. However, blending and compatibilizing did not have a positive effect on the critical stress intensity factor (Kc) of the neat PHBHH. Scanning electron microscopy (SEM) confirmed the improvement of interfacial adhesion and PBS polymer dispersion in PHBHH/PBS blends when incorporated with 5PBSgMA. The water absorption test results demonstrated that compatibilized blends absorbed slightly more water than uncompatibilized blends due to the presence of hygroscopic carboxyl groups of the PBSgMA. However, water absorption effects were reversible and did not result in severe permanent damage to the blends.

Assessment of the effect of ice-phobic impregnation composition of cement-concrete poads on the adhesive resistance of ice crust to concrete

An ice-phobic impregnation composition of cement-concrete roads has been proposed. The composition is based on keratin-containing components with the addition of a water-soluble polymer. The evaluation criterion was the study of the adhesion resistance of ice crust to concrete. The test results showed the effectiveness of the ice-phobic coating since in all experiments the uncoated samples showed greater resistance of the ice crust to thermal influences. The water absorption test results showed a significant difference in the water absorption capacity of the uncoated specimens compared to the coated specimens.

Long-term uplift of high-speed railway subgrade caused by swelling effect of red-bed mudstone: case study in Southwest China

A high-speed railway must support fast-moving vehicles and have strict low-deformation requirements. However, many high-speed railways encounter the problem of abnormal subgrade deformation caused by expansive rocks. In this study, the Neijiangbei station of the Chengdu-Chongqing high-speed railway in Southwest China, where the subgrade has undergone continuous and stable uplift during the construction and operation periods, was considered as an example. The Jurassic red-bed mudstone widely distributed in this area is a typical expansive rock, and its swelling effect is the main cause behind the uplift of the subgrade. Results of water-absorption tests, disintegration tests, and expansion tests indicate that the red-bed mudstone is characterized by easy disintegration, slow water absorption, and long-term swelling. A decoupling analysis method for the seepage and swelling of red-bed mudstone was proposed to simulate the water infiltration through the fissures and the temporal and spatial changes in the swelling. Using monitoring data, an inversion analysis of the high-speed railway subgrade uplift was conducted, and the subgrade deformation was predicted. The results suggest that the main changed area of the moisture-content field in the rock formation was a small area near the fissure layer. The moisture content of the mudstone increased rapidly in the first few years of infiltration and increased slowly over subsequent decades. Correspondingly, the subgrade uplift increased rapidly in the first few years after excavation owing to the swelling of the mudstone; thereafter, the growth rate decreased, but the subgrade uplift maintained long-term continuous growth for several decades.

Pengaruh Penambahan Fly Ash dan Serbuk Kaca Terhadap Sifat Fisik dan Mekanik Komposit Batako

Composite is a new material engineered by two or more materials where the properties of the materials differ from one another both in chemical and physical properties. Composites are obtained from a combination of metal with ceramics, metal with plastics, and others. The purpose of this study was to determine the effect of adding fly ash and glass powder on the physical and mechanical properties of brick-based composites. The drying process is carried out for 28 days. The compressive strength and water absorption tests were carried out after the drying process. The results showed the highest compressive strength value is on the B sample is 74.17 kg / cm2 and water uptake is lowest in the sample A, namely 10.53%. The highest compressive strength test results exist in the sample B is 74.17 kg / cm2 and the compressive strength is lowest in the sample A which is 66.67 kg / cm2. While the highest water absorption test results were in sample C, namely 15.05% and the lowest water absorption value was in sample A, namely 10.53%. Keywords: Brick-Based, fly ash, glass powder, compressive strength, water absorption.

Experimental Investigation for Some Properties of PMMA Denture Base Strengthened by Different Nanoadditives

In dental and medical applications, poly-methyl methacrylate (PMMA) has been widely accepted due to the excellent biocompatibility and easy fabrication. Yet, some of the physical and mechanical characteristics of this compound are considered inferior. Seven groups of PMMA nano-composite samples were reported to be fabricated at laboratory temperature . These samples could be used in manufacturing the complete or partial maxillary denture base. The aim of this research is to prepare nano-composite materials which consist of PMMA as a matrix material and two different types of powder (prepared nanoparticles of SnO2 and natural egg shell powder (ESP)) as strengthening materials. The selected additives were used in many cases as pure or hybrid composites, specifically with weight percentage ratios of 1 and 2 wt%. Several analytical tests, namely AFM, FTIR, XRD and SEM, were used on the prepared nanoparticles. In addition, several tests were applied to assess the mechanical behavior before and after the reinforcement, including thermal conductivity, Vickers micro-Hardness, and water absorption. The results showed that the maximum amount of energy absorption in the composites was 1% at different types of additives, while a significant increase in thermal conductivity was recorded as the SnO2NPs percentage was increased. For surface micro-hardness, an obvious trend of increase was observed with the increase in additive percentage. The highest measured values of micro-hardness (19.59VHS and 13.30VHS) were recorded for the pure composites of 2% ESP and 2% SnO2, respectively. The results of water absorption test showed that higher percentages of ESP and SnO2, separately, within the pure composite resulted in higher water absorption capacity and an increased value of diffusion coefficient (D).

Analysis of the Effect of Nano-SiO2 and Waterproofing Agent on the Water Transportation Process in Mortar Using NMR

Moisture diffusion in cement-based materials significantly impacts its durability. In this study, we analyzed the effect of adding a waterproofing agent and nano-SiO2 (NS) on the water transportation process in mortar using capillary water absorption tests and nuclear magnetic resonance (NMR) technology. The results indicate that the combined action of the waterproofing agent and nano-SiO2 drastically reduce the capillary water absorption coefficient and have a more significant impact than only adding the waterproofing agent. The moisture diffusion in different sections of the mortar during the water absorption process is obtained from the NMR test results and two function models. Comparative studies indicate that the NMR test results have good correlation with the capillary water absorption test results and provide accurate process data. The NMR analysis results offer a new analytical method to characterize the porosity of cement-based materials by continuously monitoring small-pitch sections.

Effect of o-MMT content on properties of Poly (vinyl chloride)/Poly (acrylonitrile styrene acrylate) blends

In this study, poly(vinyl chloride) (PVC)/poly(acrylonitrile styrene acrylate) (ASA)/ organophilic montmorillonite (o-MMT) nanocomposites were prepared and the effects of o-MMT content on the properties of PVC/ASA blends were investigated. Surface morphology studies of the o-MMT containing blends were also performed using scanning electron microscopy (SEM). The thermal stability, mechanical properties and water absorption percentage of the nanocomposites were studied. TGA test results showed that o-MMT inclusion enhanced the thermal stability of PVC/ASA/o-MMT nanocomposites and the Td50 decomposition temperature increased by 7.5 ˚C when the o-MMT content is 10 wt%. The tensile strength value of the neat blend was obtained as 32.51 MPa and found to increase as 36.01 MPa when the o-MMT content is 6 wt% in the system. The water absorption test results demonstrated that the water-resistance of the samples enhanced as the o-MMT content increased. Moreover, PVC/ASA blends experienced a significant increase in the contact angle by the presence of hydrophobic o-MMT. The weathering test results demonstrate that the PVC/ASA/o-MMT nanocomposite films can be used for outdoor applications without losing their properties too much.
