Characterization of Bamboo - Polypropylene Composites: Effect of Coupling Agent

Bamboo fibre reinforced polypropylene composites at various bamboo fibre loading levels (20 %, 30 %, 40 % and 50 %) with and without coupling agent Maleic Anhydride Polypropylene (MAPP) were prepared by extrusion and moulded in injection moulding machine. Moulded specimens were characterized by SEM, FTIR, thermal and mechanical properties. The fibre content of 50 % by weight has been proven to provide adequate reinforcement to increase the mechanical strength significantly. Thermal stability of bamboo, polypropylene and bamboo fibre reinforced polypropylene composite coupled with MAPP were analysed by using thermo gravimetric. SEM micrograph confirmed the proper interfacial adhesion between the wood fibre and PP matrix in the presence of coupling agent. Moisture absorption of coupled and uncoupled composites were compared and reported. These composites can be used in a variety of applications such as construction, automobiles, consumer goods etc. They are considered as suitable replacement for solid plastic products and materials.
