Abstract
Polyethylene (PE) composites with Kenaf fibers from the plant, Hibiscus cannabinus, provide a promising way to improve the stiffness of PE. The crystallization kinetics study of PE in the composites suggests that the interfacial bonding between Kenaf and PE appears to be unfavored. The effect of Kenaf fibers on the crystallization of PE and the tensile properties of PE/Kenaf composites are discussed in detail.
