Study of Hybridized Kenaf/Palf- Reinforced Hdpe Composites by Dynamic Mechanical Analysis.

This article presents an experimental study on the dynamic mechanical property of hybridized Kenaf/PALF-reinforced HDPE composites. Variation in storage modulus (E′), loss modulus (E″) and damping parameter (tan δ) with fiber loading and variation in fiber length were investigated. The concept of hy...
