Factors Affecting the Performance of Biocomposite: A Review

Abstract

This paper deals with the effect of various factors like compatibility of natural fibres with polymer resin, amount of fibre loading in biocomposite, orientation direction, and manufacturing process & its parameters on performance of biocomposites. In recent trend, biocomposites are a best solution for new and advanced materials development due to its non abrasive, high strength & stiffness, eco-friendly and bio-degradability characteristics. The mechanical behaviour of biocomposites is mainly influenced by interfacial adhesion between matrix and the fibres. Surface chemical modifications like graft co-polymerisation, and coupling agent are employed to enhance hydrophobicity of fibres which leads better adhesion between natural fibre and resin. In general, the tensile properties of biocomposites increase with increasing fibre content, up to an optimum value and then drop. Khothane observed that the tensile strength and Young’s modulus of bleached hemp fibre reinforced composite increased with increasing fibre content.
