Effect of fibre stacking orientation on the mechanical and thermal properties of laminated kenaf fibre/epoxy composites

ABSTRACT Natural fibre-reinforced composites have been developed by researchers and industries as a solution to reduce the use of synthetic fibres. Kenaf fibre is one of the most abundant natural fibres in Indonesia. This study aimed to obtain the mechanical and thermal properties of kenaf fibre-reinforced epoxy laminated composites fabricated using a vacuum-assisted resin infusion method. The alkaline-treated fibres were arranged in the orientations 0°/0°/0°/0° and 0°/90°/0°/90°. Density measurements, mechanical tests, and thermogravimetric analysis were carried out on the epoxy and the composites. The results of the mechanical testing showed that the tensile, flexural, and compression strengths of the kenaf fibre-reinforced epoxy composites with a 0°/0°/0°/0° fibre orientation were higher than those of the composites with a 0°/90°/0°/90° fibre orientation, with values of (96.61 ± 10.18) MPa, (131.01 ± 6.60) MPa, and (71.96 ± 5.50) MPa, respectively. Scanning electron microscope observations showed that the composites had good fibre-matrix adhesion. The thermal stability of the epoxy was enhanced from 557 °C to 571 °C by incorporating kenaf fibre with 0°/0°/0°/0° orientation. With reference to the Indonesian National Standard 01-4449–2006, the two composites could be classified as T2 45 High Density Fibreboard.

Construction of dense plasmonic hotspots on coarse Ag layer coated nylon fibers for ultrasensitive SERS sensing

Surface-enhanced Raman scattering is a powerful sensing tool effectively and rapidly to detect chemicals in environmental monitoring and food safety. Textile fiber-based surface-enhanced Raman scattering substrates have been fabricated to contribute to the practical applications of surface-enhanced Raman scattering sensing. Inspired by the metallic nanostructures with dense plasmonic hotspots which have excellent surface-enhanced Raman scattering activity, coarse silver layer coated nylon fibers are used in this study to combine with gold nanoparticles by a simple immersion method forming enriched plasmonic hotspots on textile fibers for ultrasensitive surface-enhanced Raman scattering detection. The fiber-based surface-enhanced Raman scattering substrate denoted as gold nanoparticle@silver layer coated nylon fiber shows a high sensitivity to rhodamine 6G with an excellent enhancement factor of 2.41 × 1010 and a detection limit of 10−14 M. The finite-difference time-domain simulations indicate that ultra-high sensitivity arises from the enhanced electric fields densely formed in the inter-particle and particle-film gap in the twisted gold nanoparticle@silver layer coated nylon fiber structure. In addition, the gold nanoparticle@silver layer coated nylon fiber substrate demonstrates outstanding surface-enhanced Raman scattering signal reproducibility (relative standard deviation 6.14%) as well as application flexibility. Through a simple swab procedure, gold nanoparticle@silver layer coated nylon fibers absorb rhodamine 6G molecules on apple and the detection limit can reach 10−13 M. Our results allowed us to foresee the use of synthetic fibers enriched with plasmonic hotspots in ultrasensitive wearable sensors.

Behaviour Analysis of Strengthened-RC Beam with Natural Fiber Reinforced Polymer (NFRP) based on Abaca Fiber by Using Finite Element Method

The use of synthetic Fiber Reinforced Polymer (FRP) as a composite material is an alternative material that has been widely used for strengthening and repairing reinforced concrete structures. However, the high price is one of the obstacles in applying synthetic FRP materials in developing countries such as Indonesia. Utilization of natural fiber as a Natural Fiber Reinforced Polymer (NFRP) composite material is an alternative, especially in shear strengthening of reinforced concrete beams. Because it has good tensile strength and also is environmentally friendly. Technological developments in the field of computing make modelling various aspects easier. One of them is modelling reinforced concrete (RC) beams. ATENA V534 is a software that can be used for finite element-based modelling. Therefore, in this study, the ATENA V534 software was used to evaluate the results of research and testing behaviour of reinforced concrete beams from the previous studies about strengthened beam for shear by using NFRP. Behaviour that is evaluated in the form of load and deflection, the pattern of cracks and failure, and stress and strain of reinforcements. The numerical results obtained in ATENA V534 showed in a good agreement with experimental results.

Impact of coronavirus pandemic litters on microfiber pollution-effect of personal protective equipment and disposable face masks.

Coronavirus Pandemic is the current biggest challenge against humanity. Apart from the personal health issues and higher mortality by the coronavirus, recent research works have also reported the environmental impacts of the pandemic. The review aims to analyze the current status of face masks and personal protective equipment littering and subsequent environmental impact in terms of microplastic and microfiber pollution. Recent researches in this domain are collected from the leading databases with relevant keywords and critically analyzed. The review results report a multi-fold increment in the usage of personal protective equipment, particularly face masks after the pandemic. Mismanagement of these items leads them to reach the marine environment through a variety of transportation. The results show a significant amount of increment in plastic and pandemic-related littering after the pandemic. The systematic review shows that the use of synthetic fibers in disposable personal protective equipment and masks leads to release of fibers that can add-on to microfiber pollution. The results are also true in the case of reusable masks as the repeated laundry and disinfection methods release a significantly higher amount of microfibers. Only very few studies have addressed the release of microfiber from the mask, and no studies have reported the impact of personal protective equipment. The worldwide mass adaptation and improper disposal of these materials increase the seriousness of the problem multiple folds. These findings suggest the immediate requirement of critical analysis of the pandemic-related littering and microfiber release characteristics. The research also urges the need for the implementation of an environmental management plan as a mitigation strategy around the globe.

The tensile strength of the composite using the 00 fiber direction is higher than the composite using the 900 fiber direction, which is 6.48 MPa for the Hand Lay Up method and 16.54 MPa for the Vacuum Bag method.

Functional fibers from Bambusa tulda (Northeast Indian species) and their potential for reinforcing biocomposites

Increased awareness of the environment, as well as strict laws and regulations from government agencies, have restricted the use of synthetic fiber as reinforcement. So, the engineering fraternity became more interested in natural fiber as a reinforcing material in polymer composite to create sustainable material. In the present experimental study, bamboo fiber was extracted and characterized from three different regions of bamboo culm in the radial direction, and their potentiality as reinforcing materials for bio-composites was assessed. For the first time, Bambusa tulda (a northeast Indian species) is considered for the study. The classified fiber extraction has been performed and its physical, chemical, mechanical and thermal properties have been investigated. Weibull's statistical approach has been used to analyse the physical and tensile properties of the fiber. The investigation revealed that the technical fiber extracted from the outer part (external technical fiber) of the bamboo culm has higher cellulose content (58.13 ± 3.51%), higher crystallinity index (60.142%), greater tensile strength (365.014 ± 50.441 MPa), modulus (14.098 ± 1.763 GPa), low moisture absorption capacity and higher thermal stability than fiber from the middle and inner part of the bamboo. This study will help to develop Bambusa tulda based sustainable bio-composites for futuristic applications.

Physicochemical, Thermal And Mechanical Properties of Novel Cellulosic Fiber Extracted from Ficus Retusa

ABSTRACT Natural fibers play a vital role in reducing the greenhouse gas emission caused due to the use of synthetic fibers for composite making. Many novel natural fibers with promising characteristics required for reinforcing polymer matrices remain unexplored. In the present study, an attempt has been made to bring out the potentials of novel cellulosic fiber obtained from the bark of Ficus retusa. Various tests such as chemical, X-ray diffraction, Fourier transform infrared spectroscopy, thermogravimetric, differential scanning calorimetry, tensile, energy dispersive X-ray spectroscopy and field emission scanning electron microscopy were performed on FR fibers. Cellulose (55.19 wt. %), hemicellulose (20.65 wt.%), lignin (20.87 wt.%), pectin (6.44 wt.%) and wax (2.80 wt.%) of FRFs were identified though chemical tests. X-ray diffraction revealed the crystallinity index (37.25%) and crystallite size (2.29 nm) of FRFs. Thermogravimetric analysis showed the ability of FRF to withstand 335.87°C and was found to exhibit activation energy of 64.38 kJ/mol. The tensile strength and Young’s modulus of FRF was found to be 189.50–302.50 MPa and10.31–14.37 GPa. Energy dispersive X-ray spectroscopy revealed the atomic and weight percentages of various elements present at the fiber surface. Morphology of FR fiber surface examined through FESEM confirmed the existence of rough surface with some serrations and with porous honey combed structure. Higher crystallinity index, superior mechanical properties and higher thermal stability of FRF makes them suitable for eco-friendly composite making.

Chemical treatments and mechanical characterisation of natural fibre reinforced composite materials - a review

At the present scenario, fibre composites play a vital role in fabricating components or parts used in the area of automobile, sports equipment, aerospace and biomedical, etc. Composites reinforced with natural fibres (sisal, hemp, jute, bamboo, coir, flax, etc.) enhanced the chemical and mechanical properties. The use of synthetic fibres instead of natural fibres as an alternative reinforcement is a fascinating interest to researchers and scientists all over the world because of their admirable properties such as abundantly available, low cost, less density, high specific strength, and biodegradable characteristics. However, achieving good compatibility between reinforcement and matrix is challenging during the preparation of natural fibre composites. Hence, to overcome this issue, chemical treatments are considered as the potential method to improve the fibre properties and mechanical properties such as tensile, flexural, impact, hardness and water absorption. In this present study, an overview of the various chemical treatments and mechanical characterisation of the natural fibre for utilising in fibre-reinforced polymer composites are reviewed.

Analysis of Tensile Strength of Citronella (Cymbopogon Nardus) Fiber Reinforced Composite Materials

The use of synthetic fibers in composite materials has a negative impact on the environment. One way to reduce this impact is to replace synthetic fibers with natural fibers. A natural fiber that has the potential as a mixed material in the manufacture of composite materials is citronella (Cymbopogon nardus) fiber. This study aims to determine the effect of volume fractions 40%, 50%, 60%, and 70% of citronella fiber with polyester resin matrix BQTN 157 on tensile strength. The process of making composites used the hand lay-up method. The specimen was formed according to the ASTM D3039 standard and the tensile strength of the specimen was tested by using a Universal Testing Machine (UTM). From the results of the study, the maximum tensile strength was found in the fiber volume fraction 70% of 77.35 MPa, the strain is 6.57%, and the modulus of elasticity is 1.177 GPa. This study indicates that fiber volume fraction affects the tensile strength of composite materials. Hence, the manufacture of composite materials which have good strength is influenced by many things such as raw materials, matrices, mixture composition, and methods.

Experimental Study on Engineering Properties of Cement Concrete Reinforced with Nylon and Jute Fibers

The use of synthetic fiber and natural fiber for concrete production has been continuously investigated. Most of the materials have become popular for their higher flexibility, durability, and strength. However, the current study explores the engineering properties of cement concrete reinforced with nylon and jute fibers together. Varying proportions and lengths of nylon and jute fibers were utilized in the concrete mixture. Hence, the combined effects of nylon and jute fibers on workability, density, water absorption, compressive, tensile, flexural strength, and drying shrinkage of concrete were investigated. Results showed that concrete with 1% of nylon and jute fibers together by the volume fraction showed a maximum enhancement of the compressive strength, split tensile strength, and flexural strength by 11.71%, 14.10%, and 11.04%, respectively, compared to the control mix of concrete at 90 days. However, the water absorption of concrete increased with increasing nylon and jute fiber contents. The drying shrinkage of concrete decreased with the addition of nylon and jute fibers together after 90 days. Thus, the sparing application of both nylon and jute fiber as discussed in this study can be adopted for concrete production.

Determination of Injection Molding Process Parameters using Combination of Backpropagation Neural Network and Genetic Algorithm Optimization Method

The polymer matrix composite (PMC) in use today is generally made of synthetic fibers which are expensive and not environmentally friendly. The use of synthetic fibers can be replaced with natural fibers, which are more environmentally friendly at a lower price. The natural fiber material used in this study is made from husks, with a particle size of 500 µm (mesh 35). In the PMC manufacturing process, rice husks are mixed with polypropylene (PP) and maleic anhydride polypropylene (MAPP) with a composition of 10 wt% RH, 85 wt% PP and 5 wt% MAPP. PMC materials using natural fibers are called biocomposite materials. The result of mixing PMC with natural fibers in the form of pellets is then carried out by the injection process using an injection molding machine. The printed results are in the form of tensile test specimens based on ASTM D 638-03 type V testing standards and impact test specimens based on ASTM D 256-04 testing standards. The research was conducted by optimizing the responses i.e. tensile strength and impact strength of the biocomposite material in the injection molding machine process, whereas varied process parameters, namely barrel temperature, injection pressure, holding pressure, injection velocity were selected as process parameters. The backpropagation neural network (BPNN) training method is used to recognize the pattern of the relationship between process parameters and response parameters based on the previous experiment, while the genetic algorithm (GA) optimization method is to determine the variation settings for process parameters that can optimize tensile and impact strength. The results of the BPNN training have a 4-9-9-2 network architecture consisting of 4 input layers, 2 hidden layers with 9 neurons, and 2 neurons in the output layer. Optimization with GA produces a combination of variable process parameters barrel temperature 217◦C, injection pressure 55 Bar, holding pressure 41 Bar and injection velocity 65 mm/sec. The results of statistical validation using one sample T test show that the average value of tensile strength and impact strength from the results of the confirmation experiment is the same as the value of the tensile strength and impact strength of the optimization prediction.

Natural Fibers as an Alternative to Synthetic Fibers in Reinforcement of Geopolymer Matrices: A Comparative Review.

Geopolymer materials have been gaining ground in the civil construction sector not only for having superior physical properties when compared to conventional cement, but also for being less harmful to the environment, since the synthesis of the geopolymer does not release toxic gases or require high energy costs. On the other hand, geopolymer materials like cementitious matrices have low flexural strength and have fragile breakage. To overcome these deficiencies, the insertion of fibers in geopolymeric matrices has been evaluated as a solution. Although most research on this practice focuses on the use of synthetic fibers, the use of natural fibers has been growing and brings as an advantage the possibility of producing an even more ecological material, satisfying the need to create eco-friendly materials that exists today in society. Thus, this paper aimed to, through the evaluation of research available in the literature, understand the behavior of fibers in geopolymer matrices, identify similarities and differences between the performance of geopolymer composites reinforced with natural and synthetic fibers and, understanding that it is possible, point out ways to optimize the performance of these composites.

Characterization of Timoho Fiber as a reinforcement in green composite

Synthetic fiber is more durable than most natural fibers, yet it has non-biodegradable characteristics. Biodegradable fibers such as green composites emerge as a potential substitution for non-biodegradable synthetic fibers since they are more eco-friendly and available. The natural fibers are the engineering outcomes resulting in lightweight products and good mechanical properties. They raise challenges in reinforcing green fibers as composite structures on a massive scale. This study introduces Timoho Fiber (TF) as reinforcement in preparing green composite. TF was treated with varied sodium hydroxide (NaOH) concentrations with equal immersion times. There was color alteration after TF was treated with NaOH; the TF color became brighter. The thermal resistance value was inversely proportional to the thickness value after the alkaline treatment. TF density and thermal endurance increased while TF thickness decreased along with the increase in NaOH concentration. The best crystallinity index and cellulose content were obtained with 9% NaOH. Likewise, untreated TF's tensile strength experienced a significant increase (555.26%) with 9% of alkaline treatment. The FTIR (Fourier-transform Infrared Spectroscopy) test result confirmed that alkaline treatment removed hemicellulose content, impurities, and excessive water absorption. Treated TF's surface became rougher. The etched surface indicated an interlocking with the matrix as displayed in SEM images. The positive treatment effects of NaOH on the TF show the TF's potential as green composites reinforcement to reduce the use of synthetic fibers.

A Study of the Flexural Behavior of Fiber-Reinforced Concretes Exposed to Moderate Temperatures.

The use of synthetic fibers in fiber-reinforced concretes (FRCs) is often avoided due to the mistrust of lower performance at changing temperatures. This work examines the effect of moderate temperatures on the flexural strengths of FRCs. Two types of polypropylene fibers were tested, and one steel fiber was employed as a reference. Three-point bending tests were carried out following an adapted methodology based on the standard EN 14651. This adapted procedure included an insulation system that allowed the assessment of FRC flexural behavior after being exposed for two months at temperatures of 5, 20, 35 and 50 °C. In addition, the interaction of temperature with a pre-cracked state was also analyzed. To do this, several specimens were pre-cracked to 0.5 mm after 28 days and conditioned in their respective temperature until testing. The findings suggest that this range of moderate temperatures did not degrade the behavior of FRCs to a great extent since the analysis of variances showed that temperature is not always a significant factor; however, it did have an influence on the pre-cracked specimens at 35 and 50 °C.

The spontaneous urbanisation has brought about boom in call for of land, solid for fast and green buildings over it. Hence it's far critical to bolster low bearing potential regions for financial creation practices.To conquer this impediment numerous laboratory tests and research are carried out, comparing the reinforceing impact of geogrid for enhancing bearing potential of soil. This paper objectives to look at the impact of artificial fibrein improving the bearing potential. Krishna river sand is used at exceptional relative density of compaction and handiest one kind of artificial fibre have been used for the tests. The intensity of the muse become various from 0 to B (B=width of foundation). The increase with inside the bearing potential with the availability of synthetic fibre as reinforcement is observed.

Influence of stacking sequence and orientation of the fabric on mechanical properties of twill Kenaf/Kevlar reinforced unsaturated polyester hybrid composites

The current study investigates on development of hybrid composite with Kenaf/Kevlar as reinforcement and unsaturated Polyester as the matrix considering stacking sequence, the orientation of fabric and twill 2x2 weave of the Kenaf fabric in particular. Five laminates (L1, L2, L3, L4, and L5) were developed by stacking the lamina's one over the other with the matrix and then cured in an autoclave. The laminates were subjected to experimental investigation to evaluate mechanical properties such as tensile strength, flexural strength, hardness, and impact strength. Results indicate that L5 shows good flexural strength and modulus, high hardness, and good impact strength, whereas L4 indicates the best tensile strength and tensile modulus. To summarize, the hybridization resulted in an average of 30% increased mechanical property for Laminate L5. The effect of stacking in L5 has a significant impact on the property of the composite. The results of the study were mainly focused on minimizing the use of synthetic fiber and replacing it with natural fiber. SEM analysis was performed on fractured surfaces of specimens which revealed that the failure of the laminated composite is due to poor interfacial bonding among fiber and matrix. Overall, the composite obtained from the combination of Kenaf and Kevlar fabrics had the best balance of properties finds appropriate application for car bumpers, fenders, boat hull, turbine blade etc.

Self-Healing Potential and Post-Cracking Tensile Behavior of Polypropylene Fiber-Reinforced Cementitious Composites

The use of synthetic fibers as reinforcement in fiber-reinforced cementitious composites (FRCC) demonstrates a combination of better ductile response vis-à-vis metallic ones, enhanced durability in a high pH environment, and resistance to corrosion as well as self-healing capabilities. This study explores the effect of macro- and micro-scale polypropylene (PP) fibers on post-crack energy, ductility, and the self-healing potential of FRCC. Laboratory results indicate a significant change in fracture response, i.e., loss in ductility as curing time increases. PP fiber samples cured for 2 days demonstrated ductile fracture behavior, controllable crack growth during tensile testing, post-cracking behavior, and a regain in strength owing to FRCC’s self-healing mechanism. Different mixes of FRCC suggest an economical mixing methodology, where the strong bond between the PP fibers and cementitious matrix plays a key role in improving the tensile strength of the mortar. Additionally, the micro PP fiber samples demonstrate resistance to micro-crack propagation, observed as an increase in peak load value and shape deformation during compression and tensile tests. Notably, low volume fraction of macro-scale PP fibers in FRCC revealed higher post-crack energy than the higher dosage of micro-scale PP fibers. Lastly, few samples with a crack of < 0.5 mm exhibited a self-healing mechanism, and upon testing, the healed specimens illustrated higher strain values.

Delamination and Manufacturing Defects in Natural Fiber-Reinforced Hybrid Composite: A Review.

In recent years, most boat fabrication companies use 100% synthetic fiber-reinforced composite materials, due to their high performance of mechanical properties. In the new trend of research on the fabrication of boat structure using natural fiber hybrid with kevlar/fiberglass-reinforced composite, the result of tensile, bending, and impact strength showed that glass fiber-reinforced polyester composite gave high strength with increasing glass fiber contents. At some point, realizing the cost of synthetic fiber is getting higher, researchers today have started to use natural fibers that are seen as a more cost-effective option. Natural fibers, however, have some disadvantages, such as high moisture absorption, due to repelling nature; low wettability; low thermal stability; and quality variation, which lead to the degradation of composite properties. In recent times, hybridization is recommended by most researchers as a solution to natural fiber’s weaknesses and to reduce the use of synthetic fibers that are not environmentally friendly. In addition, hybrid composite has its own special advantages, i.e., balanced strength and stiffness, reduced weight and cost, improved fatigue resistance and fracture toughness, and improved impact resistance. The synthetic–nature fiber hybrid composites are used in a variety of applications as a modern material that has attracted most manufacturing industries’ attention to shift to using the hybrid composite. Some of the previous studies stated that delamination and manufacturing had influenced the performance of the hybrid composites. In order to expand the use of natural fiber as a successful reinforcement in hybrid composite, the factor that affects the manufacturing defects needs to be investigated. In this review paper, a compilation of the reviews on the delamination and a few common manufacturing defect types illustrating the overview of the impact on the mechanical properties encountered by most of the composite manufacturing industries are presented.

Development of Utilization Alkali-Treated Bamboo Fiber as a Strengthener in Thermoset and Thermoplastic Composites

The increasing concern over environmental problems and the demand for renewable raw materials continues to increase, making researchers must find the right solution to overcome these problems. One solution is to reduce the use of synthetic fibers, which can replace natural fibers. This article is to review the use of bamboo fiber as a reinforcement to improve the physical and mechanical properties of composites, starting from the manufacturing process to its future potential. The matrix, which usually used as a binder of bamboo fiber, is thermoset and thermoplastic. As time goes by, the matrix becomes more popular. The method of making composites with Hot Press has a significant effect on composite results. The preparations and parameters involved during the process of making bamboo fiber composites with thermoset and thermoplastic matrices have a considerable impact on the results of the physical and mechanical properties of composites. Alkali treatment can eliminate hemicellulose, lignin, wax, and oil, which cover the surface of the outer walls of natural fiber cells and increase the surface roughness of the fibers, thereby increasing the bond between the polymer and the fiber. The determination of fiber composition variation plays a significant role in the physical and mechanical properties of composites. Too much pressure can damage the fiber, while too low pressure results in poor lamination consolidation. The processing temperature results in a better interface wetting between the fiber and the matrix. Holding time produces a more reliable bonding interface by removing the air gap that induced during pressing between the fiber and the matrix, thereby increasing tensile strength and modulus. The utilization of bamboo fibers to reduce synthetic fibers has opened opportunities for academics and industry to design sustainable modules to utilize bamboo fibers in the future. Making bamboo fiber-based composites with thermoset and thermoplastic matrices can reduce environmental problems and can be developed into effective biocomposites. Added with the advantages of thermosets and thermoplastics such as resistance to heat and chemicals even in extreme environments, flexible and recyclable, so that it has good potential in the future.

Characteristic Study on Sisal Fibre Hybrid Composites Filled With Nano SiO2 and Marble Dust Particles

The synthetic fibres are having high stiffness and strength still high manufacturing cost with environmental issues limited the use of synthetic fibres. This encourages towards thinking of intense research of natural fibres having similar property as synthetic fibres. To obtain the better mechanical and thermal property, hybridization of fibres is mostly preferred and that leads to minimize the use of synthetic fibres. As natural fibres are strong and having more ductile property, though moisture absorption is the primary limitation. So fibres is subjected to various treatments such as physical, thermal, chemical and laser treatments etc., to improve the surface characteristics with better interfacial bonding. Nano particle addition also helps in improving the performance of composites and develops cross linking in bonding of matrix and fibre. This research work mostly focuses on hybridization of short mercerized sisal and glass fibre filled with nano silica and marble dust particles, by injection moulding process with polypropylene matrix. It is noticed that among the addition of different fillers, marble dust added composite gave the better result than SiO2 added composite. Incorporation of SiO2 particles as filler material improves the flexural strength and thermal property of the composite.
