“…Extensive studies were done on natural fibers to see if they could replace synthetic fibers, and the results showed that they could be a promising reinforcing agent for polymer matrix composites. In comparison to synthetic fibers, natural fibers have various advantages such as being lightweight, low in density, cheaper, renewable, and biodegradible [1][2][3][4][5][6][7][8][18][19]. Natural fibers are also abundantly available in certain countries like India [20].…”

“…Despite their significant values, natural fibers are not strong enough to be used on their own, and they can easily absorb moisture in either humid environment or immersed in water. This causes incompatibility between the hydrophilicity of fibers and the hydrophobic behavior of polymer matrix [2][3][4][5][6][7][8]19]. The hydrophilic property of the natural fiber is due to the presence of hydroxyl groups in the cellulose which will lead to poor adhesion with polymer matrix, and poor mechanical, physical, and thermal properties of a composite.…”

“…Advanced sustainable materials such as natural fiber reinforced polymer (NFRP) composites are currently a famously investigated topic due to their less environmental impact, energy consumption during fabrication, and recyclability [2][3][4][5]. The use of natural fibers, like bamboo, kenaf, hemp, sisal, and banana for polymer composites reinforcement are significant in various industries such as automotive, construction, aerospace, electronics, etc [6][7]. The advantages of natural fibers are the availability of a variety of fibers, low cost, and density, lightweight, renewability, biodegradability, and environmentally friendly.…”

“…However, these fibers have some drawbacks i.e., poor compatibility and wettability, sensitivity to high temperature, and moisture absorption which will affect the properties and performance of the composites. These drawbacks can be eliminated by treatments after extraction [1][2][3][4][5][6][7][8].…”

Advanced sustainable materials with high performance are garnering a lot of attention nowadays due to rising environmental concerns. Natural fiber reinforced polymer (NFRP) composites are currently one of the huge demands to replace conventional materials as it inhibits great properties, low cost, abundantly available, and environmentally friendly. There are various ways to fabricate NFRP composites such as compression molding, resin transfer molding, etc. However, these methods have several disadvantages (e.g., non-uniform temperature distribution, longer processing time, and high cost). This paper reviews the current trend of utilizing microwave curing in fabricating NFRP as it provides volumetric heating, less power consumption, and is more efficient.

“…Of the 13 fiber types tested, kenaf fiber turned out to be the best option which fulfills performance requirements and the design objectives. Dattatreya et al [ 10 ] studied the mechanical properties of hybrid composites made of waste natural fibers or fillers and epoxy resin. The research included composites with jute fiber, coconut coir, sugarcane, and neem wood powder.…”

Hybrid composites, usually combining natural and synthetic reinforcing filaments, have gained a lot of attention due to their better properties than traditional two-component materials. For structural applications of hybrid composites, there is a need to precisely determine their mechanical properties on the basis of the mechanical properties, volume fractions, and geometrical distributions of constituent materials. The most common methods, such as the rule of mixture, are inaccurate. More advanced methods, giving better results in the case of classic composites, are difficult to apply in the case of several types of reinforcement. In the present research, a new estimation method is considered, which is simple and accurate. The approach is based on the definition of two configurations: the real, heterogeneous, multi-phase hybrid composite configuration, and the fictitious, quasi-homogeneous one, in which the inclusions are “smeared out” over a representative volume. A hypothesis of the internal strain energy equivalence between the two configurations is formulated. The effect of reinforcing inclusions on the mechanical properties of a matrix material is expressed by functions of constituent properties, their volume fractions, and geometrical distribution. The analytical formulas are derived for an isotropic case of a hybrid composite reinforced with randomly distributed particles. The validation of the proposed approach is performed by comparing the estimated hybrid composite properties with the results of other methods, and with experimental data available in the literature. It is shown that a very good agreement is obtained between experimentally measured hybrid composite properties and their predictions resulting from the proposed estimation method. The estimation errors are much lower than the errors of other methods.

Natural fiber-reinforced epoxy composites (NFRCs) have gained significant attention in recent years due to their potential as environmentally friendly and sustainable materials. These composites combine natural fibers, derived from plants, with epoxy resins to create a material with enhanced properties. The objective of this study is to investigate the mechanical, wear and thermal properties of NFRCs incorporating cotton, sisal, coir and wool fibers. The vacuum-assisted resin transfer molding (VARTM) technique was employed to produce composite plates, followed by conducting tests on tensile, wear and thermal properties. The cotton composite showcased the highest tensile strength, reaching 52.81 MPa, while the coir composite exhibited the lowest, measuring 15.34 MPa. Sisal composite exhibited a moderate wear rate (1.423 mm3/Nm) and a lower coefficient of friction (0.233), implying smoother relative motion. Coir composite presented the highest wear rate (4.615 mm3/Nm), attributed to its coarse fiber nature. Thermal conductivity is highest at cotton composite (1.017 W/mK) and is lowest at coir composite (0.187 W/mK). Additionally, the highest specific heat was observed in the coir composite (26.313 MJ/m3K). Cotton demonstrated potential for efficient heat transfer, while wool outperformed in insulation. Sisal displayed versatility for structural applications. Coir emerged as an effective insulator with energy-saving applications.
