Natural fiber such as bamboo fiber, oil palm empty fruit bunch (OPEFB) fiber, kenaf fiber, and sugar palm fiber-reinforced polymer composites are being increasingly developed for lightweight structures with high specific strength in the automotive, marine, aerospace, and construction industries with significant economic benefits, sustainability, and environmental benefits. The plant-based natural fibers are hydrophilic, which is incompatible with hydrophobic polymer matrices. This leads to a reduction of their interfacial bonding and to the poor thermal stability performance of the resulting fiber-reinforced polymer composite. Based on the literature, the effect of chemical treatment of natural fiber-reinforced polymer composites had significantly influenced the thermogravimetric analysis (TGA) together with the thermal stability performance of the composite structure. In this review, the effect of chemical treatments used on cellulose natural fiber-reinforced thermoplastic and thermosetting polymer composites has been reviewed. From the present review, the TGA data are useful as guidance in determining the purity and composition of the composites’ structures, drying, and the ignition temperatures of materials. Knowing the stability temperatures of compounds based on their weight, changes in the temperature dependence is another factor to consider regarding the effectiveness of chemical treatments for the purpose of synergizing the chemical bonding between the natural fiber with polymer matrix or with the synthetic fibers.

In this research, the effect of siliconized chitosan biopolymeric particles and morinda fiber in epoxy composite and their mechanical and machining behavior were studied. The primary aim of this research was to investigate how the silane‐treatment influences the surfaces of natural biopolymeric particle and fiber in epoxy composite and to study the mechanical and machining behavior. The chitosan and morinda fibers were surface‐treated using an amino silane 3‐Aminopropyltrimethoxylane (APTMS) via aqueous solution method. The composites were prepared using the hand lay‐up method followed by post‐curing at 120οC. The mechanical results showed that the silane surface‐treated chitosan and morinda natural fiber‐reinforced epoxy composite gives improved tensile, flexural and impact results of 148 MPa, 163Mpa and 6.9 J respectively. The inter‐laminar shear strength of silane‐treated morinda fiber gave the highest value of 28 MPa. Similarly, in the drilling process, the surface‐treated reinforcements showed the highest adhesion with matrix without any delamination. The drilled hole dimension stability at the top and the bottom surface was significantly high for silane‐treated epoxy composites. The scanning electron microscope images revealed high adhesion of fiber and uniform dispersion of chitosan particle in the epoxy matrix. Hence, this study confirms that silane surface‐treatment is an essential process while making high‐performance natural composites for various engineering applications.

High toughness epoxy resin hybrid composites were prepared using nanoclay, SiC, and glass-caryota intra ply fibers. The main aim of this research was to study the effect of adding Caryota urens natural fiber from biomass as a potential fiber along with synthetic glass fiber in load-bearing and wear properties of nanoclay and silicon carbide (SiC) particle toughened epoxy composite. The intra-ply glass-caryota fiber, silicon carbide, and nanoclay were surface-treated using 3-Aminopropyltrimethoxysilane. The composites were prepared using the hand lay-up method. The tensile result shows that the addition of 1 vol% of the silicon carbide particle along with nanoclay in intra-ply glass-caryota fiberreinforced epoxy composite gives improved results than other composite designations. The wear properties show that the addition of silicon carbide of 1.0 vol% gives a lower specific wear rate of 0.024 mm 3 /Nm. Similarly, the composite, which contains 1.0 vol% of silicon carbide and nanoclay gives higher penetration resistance and energy absorption. In all properties, the addition of silicon carbide modifies the values significantly. This high toughness intra-ply glass-caryota fiber-reinforced silicon carbide/nanoclay toughened epoxy resin composite could be used in automotive, sports components, domestic appliances, and structural body applications.
