Properties of kenaf/polypropylene composites

Abstract

Combining kenaf fiber with other resources provides a strategy for producing advanced composite materials that take advantage of the properties of both types of resources. It allows the scientist to design materials based on end-use requirements within a framework of cost, availability, recyclability, energy use, and environmental considerations. Kenaf fiber is a potentially outstanding reinforcing filler in thermoplastic composites. The specific tensile and flexural moduli, for example, of a 50% by volume of kenaf-polypropylene (PP) composite compares favorably with a 40% by weight of glass fiber-PP injection molded composite. Results indicate that kenaf fibers are a viable alternative to inorganic/mineral- based reinforcing fibers as long as the right processing conditions and aids are used, and for applications where the higher water absorption of the lignocellulosic- based fiber composite is not critical.
