Extraction, Characterization and Suitability Examination of Tinospora Cordifolia (TC) Fibers for Their Applicability as Reinforcement in Composite Materials

The study focused on extracting and characterizing natural cellulose fibers from Tinospora Cordifolia (TC) for use as reinforcement in composite materials. The extraction process involved several steps including plant material selection, fiber separation, and purification. The resulting fibers were characterized using various techniques such as Fourier Transform Infrared spectroscopy, X-ray diffraction, and scanning electron microscopy. This research showed that the extracted cellulose fibers had high crystallinity and a uniform diameter, making them suitable for use as reinforcement in composites as experimented two samples with 22.6 and 25.7% of Hemicellulose, 41.26 and 41.96% of Cellulose and 23.66 and 22.7% of Lignin. The study concludes that TC is a promising source of natural cellulose fibers for composite reinforcement. The mechanical properties of the composites reinforced with TC cellulose fibers were evaluated and compared with those of conventional synthetic fibers. It was found that the composites reinforced with TC cellulose fibers exhibited superior mechanical properties, such as higher tensile strength and improved flexibility. This highlights the potential of natural cellulose fibers as a sustainable alternative to synthetic fibers in the composite industry. The extraction and characterization of natural cellulose fibers from TC demonstrate their potential as reinforcement in composite materials. The study provides valuable information for future research and development in the area of natural fibers for composite reinforcement. The utilization of TC cellulose fibers in composites not only improves their mechanical properties, but also provides a sustainable and eco-friendly solution to traditional synthetic fibers.

Flexural strength and flammability of pineapple leaf fiber (PALF)/fire retardants reinforced polymer composites

The use of natural fibers as reinforcement in composite materials, such as pineapple leaf fiber (PALF), has been extensively studied. However, it is important to note that natural fiber-reinforced polymer composites are often associated with high flammability. The aim of this paper is to investigate the mechanical properties and fire retardancy of Pineapple Leaf Fiber (PALF) reinforced polymer composites treated with various flame retardants. The PALF composites were treated with different fire-retardant additives, including ammonium polyphosphate (APP), aluminum hydroxide (ALH), and magnesium hydroxide (MH), at varying ratios (10 wt%, 20 wt%, and 30 wt%). The flexural properties of the PALF composites were assessed using a Universal Testing Machine (UTM) in accordance with ASTM D7264. The flammability testing was conducted following the Underwriters Laboratories 94 (UL-94) using standard ASTM D635 and ASTM D3801. The results of flexural tests indicated that PALF-reinforced polymer composites containing 10% MH as fire retardant exhibited the highest flexural strength (102.96 MPa). Scanning Electron Microscopy (SEM) was employed to analyze the fracture behavior of PALF-reinforced polymer composites with different fire-retardant additives. The SEM analysis revealed various characteristics including fiber pull-out, fiber breakage, inhomogeneous structural distribution (in cases of APP, MH, ALH), presence of undesired bubbles, and fiber–matrix cracking. In terms of fire retardancy, the most promising results were obtained with the addition of 20% and 30% APP. These compositions achieved V-1 and V-0 ratings respectively, in the vertical UL-94 flammability test. Notably, the horizontal test demonstrated that the composites containing 30% APP did not sustain burning and exhibited no burning rate. Similarly, the composite with 20% APP self-extinguished before the first mark without any observable burning rate.

Lignin Degradation of Kapok Fiber (Ceiba pentandra, L) with Different Times of Pulping

Lignin reduced the adhesion between the polymeric matrix and natural reinforcement in composite materials by its hydrophobic characteristic. Removal of lignin can be a solution to improve fiber function in composite use. This study aimed to determine the degradation of lignin at different times of pulping. The soda process was conducted at 60, 70, 80, 90, and 100 minutes of pulping using heat in a room atmosphere. Yields, lignin content, and lignin spectrum (FT-IR analysis) were measured. The result showed the highest degradation of lignin was in 100 minutes of pulping with 80.34% lignin degradation and 3.57% lignin left in fibers. However, the yield of fibers decreased with increasing pulping time due to lignin removal. 100 minutes of pulping time showed the highest loss of fiber yield. This study showed the best pulping time for kapok fiber is 100 minutes with 3.57 % lignin remaining in the pulp.

Large lattice mismatch of nanocomposite coating: In-situ establishment of MoS2 by precursor and desulfurization reaction

Constructing large lattice mismatch interfaces, especially two-dimensional materials such as MoS2, is the key to reaching the structural lubricity of heterogeneous structures. Large lattice mismatch prevents the nucleation of reinforcement of composite material, such as in situ synthesized MoS2 during the PEO process, thus affecting the mechanical performance. In this work, a precursor reaction, which can form an amorphous MoS3/TiO2 mixtures, is proposed, and the MoS2/TiO2 noncoherent interface with large mismatch is obtained through solid-state in situ desulfurization of suspended S with the action of reheat. Meanwhile, the precursor reaction is strongly dependent on the sulfur source concentration, which can form the interface with a large number of interfacial dislocations by regulating the concentration of sulfur source. Such edge pining noncoherent interface enables more dislocation and distortion near interface during scratch, which reduces the twist-angle dependence thus further improving the tribological properties. Additionally, these results render the herein presented amorphous precursor reaction strategy generally applicable for exhibiting broad application of in situ synthesis of reinforcement.

Ballistic Performance, Thermal and Chemical Characterization of Ubim Fiber (Geonoma baculifera) Reinforced Epoxy Matrix Composites.

The search for unexplored natural materials as an alternative to synthetic components has driven the development of novel polymeric composites reinforced with environmentally-friendly materials. Natural lignocellulosic fibers (NLFs) have been highlighted as potential reinforcement in composite materials for engineering applications. In this work, a less known Amazonian fiber, the ubim fiber (Geonoma baculifera), is investigated as a possible reinforcement in epoxy composites and was, for the first time, thermally characterized by thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC). Additionally, its chemical structure was elucidated by Fourier transform infrared spectroscopy (FTIR). Ballistic tests were also performed against the threat of a 7.62 mm high-speed lead projectile. The results were statistically analyzed by the Weibull statistical analysis method. FTIR analysis showed the functional groups normally found for NLFs highly rich in cellulose, hemicellulose, and lignin. The TGA/DTG results showed the onset of thermal degradation for the composites (325~335 °C), which represents better thermal stability than isolated ubim fiber (259 °C), but slightly lower than that of pure epoxy (352 °C). The DSC results of the composites indicate endothermic peaks between 54 and 56 °C, and for the ubim fibers, at 71 °C. Ballistic tests revealed higher energy absorption in composites with lower fiber content due to the more intense action of the brittle fracture mechanisms of the epoxy resin, which tended to dissipate more energy. These failure mechanisms revealed the presence of river marks, cracks, and broken fibers with a detachment interface. These results may contribute to the production of ubim fiber-reinforced composites in engineering applications, such as ballistic armors.

Impact of yarn compositions, loop length, and float stitches on the mechanical behavior of knitted fabrics via full factorial design and RSM

This article presents a study on the tensile properties of knitted fabrics commonly employed in polymeric matrix textile composites. The key mechanical parameters investigated include stress (Pa), strain, Young's modulus (Pa), and work of rupture (J). The knitted fabrics were developed using the Cixing Knitting System software and subsequently manufactured using a double jersey (electronic) flat knitting machine. The primary objective of this research was to explore the impact of various factors on the mechanical behavior of these knitted fabrics. The factors studied were wale and course directions, float stitch density, loop length (cm), and the type of synthetic knitting yarns used (100% polyester and 100% polyamide) along with different combinations of knitting yarns (100% cotton and 67% polyester/33% cotton hybrid). The adopted ASTM D 5034 standard, Response Surface Methodology (RSM), and Analysis of Variance (ANOVA) were employed to evaluate the mechanical performance of these fabric structures. The findings of the study revealed that the statistical adjustment of the data set for stress, strain, Young's modulus, and work of rupture in knitted fabric structures significantly reduced the standard deviations for mechanical responses. This information holds particular significance as it pertains to the frequent use of these knitted fabric structures as reinforcement in textile-reinforced composite materials. Overall, this study sheds light on the mechanical behavior in structures of knitted fabrics used in polymeric matrix composites, providing valuable insights for the design and optimization of advanced textile-based materials.

Nanoindentation and nano-scratch testing on cement paste

Carbon nanotubes are an attractive reinforcement material for several composites. This is due to their inherently high tensile strength and high modulus of elasticity. This study focused on the nanomechanical characteristics of cement paste with and without short multi-walled carbon nanotubes (MWCNTs). The objective behind studying the nanomechanical properties of cement paste is to better understand the fundamental behaviour of cement at the nanoscale level. Cement paste is a complex material that consists of various phases, including cement hydrates, unhydrated cement particles and porosity. By studying the mechanical properties of cement paste at the nanoscale, researchers can gain insights into the mechanisms that govern the behaviour of this material. Following earlier tests, the amount of MWCNTs was kept constant (0.30% by weight of cement). The nanomechanical parameters explored included the localised Young's modulus and hardness. According to the test results, short MWCNTs increased the proportion of high-density calcium silicate hydrate in the cement paste. The nanomechanical properties (localised Young's modulus and hardness) of cement paste with short MWCNTs were found to be greater than those of cement paste without MWCNTs. According to nano-scratching experiments, the cement matrix with short MWCNTs was substantially more durable than the matrix without them.

Wear properties of graphene-reinforced aluminium metal matrix composite: A review

Abstract The recent advancement in graphene-reinforced aluminium matrix composites improves wear behaviour in the production of lightweight and high-performance nanocomposites. Considerable works have been devoted to using graphene nanoparticles as solid self-lubricants to increase wear resistance, minimise friction coefficients, improve service efficiency, and extend the lifespan of related sliding components. In general, wear behaviour often depends on the homogeneous distribution of graphene in the aluminium matrix. The non-uniform distribution of reinforcement due to the tendency of graphene to agglomerate in aluminium matrix and its poor wettability becomes a challenge in developing optimum functional of composites. The wettability of graphene can be enhanced by proper processing methods and sufficient addition of magnesium that can improve the wear and frictional properties of the produced composites. Hence, this review article provides recent findings and the influence of graphene as reinforcement materials in composites, including the effects on wear behaviour and friction properties. This article also discusses new advancements in the effect of graphene in self-lubricating aluminium matrix composites and the impact of reinforcement on the wear mechanisms of the composites. The future direction of the wear properties of MMCs is also covered at the end of the review.

Coffee is one of the most valued agricultural products regarding its high commercialization rate. During the production of coffee beans, coffee pulp is obtained as one of the main byproducts with a cellulose content of more than 30% of dry weight. This research focused on the value-added potential of coffee pulp fiber as the reinforcement in composite materials. The nanocellulose coffee pulp (NCP) from the coffee pulp (CP) was prepared and subsequently used as a filler to reinforce the polyvinyl alcohol (PVA) matrix for the improvement of PVA composite properties. The CP was treated via alkali and bleaching treatment before the production of NCP using the acid hydrolysis treatment. The TEM result of NCP showed the successful preparation of NCP with an average diameter of 16.03 ± 4.70 nm with increasing crystallinity size and crystallinity index. The effect of glycerol (G) in the PVA matrix was observed. The result showed that glycerol had a play-role as a plasticizer for increased flexibility and decreased hardness and brittleness of PVA nanocomposite film. The nanocomposite film of PVA/G/NCP was fabricated with various ratios of NCP through the casting method. It was shown that the physical properties were improved with the presence of NCP in the PVA matrix compared to the neat PVA film.

Investigation into the mechanical characteristics of natural fiber-reinforced polymer composites: Effects of flax and e-glass reinforcement and stacking configuration

Glass fibers are commonly used to reinforce polymer composites due to their excellent mechanical properties. However, their production is expensive and environmentally unfriendly. To tackle these concerns, researchers are exploring natural fibers as a substitute reinforcement material for polymer composites. These natural fiber-reinforced polymer composites are lightweight, possess a high strength-to-weight ratio, and are biodegradable, making them attractive for a wide range of applications such as automotive, marine, oil, consumer goods, sporting goods, and biomedical fields. In this study, the hybrid effects of using flax and E-glass as reinforcement in epoxy, as well as the stacking configuration of flax/E-glass, on the mechanical properties of the polymer composites were investigated. Laminates with different fiber loadings were created using hand layup vacuum bagging and then subjected to tensile testing following ASTM standards. Statistical analysis tools such as interval graphs, contour plots, surface plots, probability plot, and Pareto chart were employed to assess the impact of the fiber and other parameters. Regression analysis was conducted to develop an empirical equation with a 95 percent confidence limit for all intervals. The results indicated that the properties of the polymer composites exhibited slight improvement from pure epoxy to flax/epoxy composites, significant improvement with E-Glass/epoxy composites, and slight decrease with hybridization. Nevertheless, the hybrid composite still demonstrated much higher tensile strength compared to the pure and flax/epoxy composites. The stacking configuration with treated flax as the core and E-Glass as the skin layer resulted in a tensile strength of 164.23 MPa, surpassing that of flax/epoxy and pure epoxy composites. In conclusion, for medium load structural applications, flax/E-glass/reinforced epoxy composites are recommended through hybridization. The utilization of natural fibers as reinforcement in polymer composites presents a cost-effective and environmentally friendly alternative to glass fibers, while still providing the necessary mechanical properties for various applications.

Biodegradable Polyethylene-Based Composites Filled with Cellulose Micro- and Nanoparticles

Composite materials filled with cellulose particles (microcrystalline cellulose and nanocellulose) have good prospects for use in various fields. Microcrystalline cellulose (MCC) and nanocellulose (NC) were isolated by chemical and physical methods and investigated. Composite materials based on polyethylene (PE) were obtained using MCC and NC as fillers (5–20 wt.%) and maleic anhydride grafted low molecular weight polyethylene (MA-g-LMPE) as a compatibilizer. The structure and morphology of the composites and fillers were characterized by Fourier transform infrared (FTIR) spectroscopy, X-ray diffraction, thermal analysis (TA), transmission electron microscopy (TEM), atomic force microscopy (AFM), and the strength properties were determined by tensile testing. An increase in the crystallinity index and mechanical strength of composites at low filler contents (up to 5 wt.%) was revealed. The size of the cellulose particles significantly affects the structure and properties of composites. Although the general picture of the effect of fillers on the crystalline structure and mechanical properties is similar, the addition of NC had a greater effect than МСС. The results of this study showed the possibility of using MCC and NC as reinforcement materials in composites, and they have biodegradable properties.

The development of composite reinforced hybrid fiber musa acuminata stem-hibiscus tiliaceust bark with filler liquid rubber as vehicle bumper

The characterized of the polyester composites reinforced of the hybrid fiber musa acuminata stem fiber (MASF)-hibiscus tiliaceust bark fiber (HTBF) with liquid rubber filler was studied. The object of research is the polyester composite material, hybrid natural fiber reinforcement and filler Carboxyl Terminated Butadiene Acrylonitryle (CTBN). The polyester composite material which is used as a vehicle bumper, is easily broken and has low heat resistance so that its shape easily changes/shrinks due to heat. This research aims to develop the tensile strength, impact toughness and heat resistance of polyester composites. The reason for using the MASF-HTBF hybrid fiber as a reinforcement for polyester composite materials is because MASF and HTBF are natural fibers that have great potential to be developed to improve the mechanical properties of polyester composites, as substitutes for synthetic fibers. In this study, the conditions of MASF and HTBF were given alkaline treatment by immersing them in 5 % NaOH solution for 24 hours then drying. The combined/hybrid ratio between the MASF and CTBF volume fractions is: 5 %:25 %, 10 %:20 % and 15 %:15 %. To increase impact toughness, CTBN filler is added with variations of 5 %, 10 %. The mechanical characteristics of the specimens were carried out by means of a tensile test and an impact test. The change in mass or shrinkage as a result is tested by TGA. The results showed that the MASF-HTBF hybrid fiber-reinforced polyester composite material with CTBN filler has better mechanical properties than single natural fibers, so it is important to develop it further as a material for making vehicle bumper

The aim of this investigation is to evaluate the use of new lignocellulosic fiber extracted from Centaurea hyalolepis plant as a potential reinforcement for light-weight composite applications. In this study, anatomical structure and morphological surface of Centaurea hyalolepis fiber were conducted. The physical-chemical, thermal, crystalline,mechanical, characteristics of extracted fibers were also examined using Attenuated Total Reflectance-Fourier Transform Infrared (ATR-FTIR), thermogravimetric analysis (TGA), X-ray diffraction (XRD) and tensile test. ATR-FTIR analysis confirmed the existence of the main components of lignocellulosic fiber (lignin, cellulose, and hemicellulose). XRD revealed the presence of cellulose with a crystallinity index of 57.93%.By densimetry, the density of Centaurea hyalolepis was determined as 1.13 g/cm3. The Centaurea hyalolepis was found to be thermally stable up to 271°C. The kinetic activation energy was determined as 115.943 kJ/mol. Tensile tests revealed that the mean tensile strength and Young’s modulus of Centaurea hyalolepis fiber were about 372,5 MPa and 9.036 GPa respectively. Because of the dispersion in the experimental tensile results, the Weibull statistical analysis with two parameters was carried out. Regard these findings, the Centaurea hyalolepis fibers can be a suitable candidate for low density polymeric composites reinforcement.
