A critical review of different properties of natural fibre-reinforced composites

The eco-friendly and sustainable nature of bio-based fibres has received much interest from analysts to incorporate them into the polymer matrix. The research of filled plastic composites has sparked much attention in the recent decade as a way to address the lack of petroleum resources. The use of plastic has been prominent in almost everything, from ordinary things to complicated structures and industrial parts. Natural fibres entice researchers and scientists want to use their qualities by reinforcing them with polymers. Fibre loading percentage, size and orientation of fibres, stacking sequences, degree of interfacial adhesion, fibre surface treatments, hybridization, and integration of fillers and coupling agents all influence the qualities of natural fibre-reinforced polymer composites. The article summarizes different chemical remedies affecting natural fibres to enhance their qualities. Effects on water absorption and tribological behaviour caused by chemical therapies were included in this study. As a result, the natural fibre-reinforced composites' mechanical characteristics have also been discussed in the present study.
