Effect of Interface Improving on Morphology and Properties of Coir Fiber/LLDPE Bio-Composites

Abstract:

The mechanical properties of coir fiber/line low density polyethylene (LLDPE) bio-composites were studied and micrographs of fracture surface of impact specimens for the composites were analyzed by scanning electron microscope (SEM). The flexural and impact strength of the composite with a compatilizer were higher than that of the composite without a compatilizer. The results of interface morphology of the composites with a compatilizer show better interfacial adhesion than that of the composites without one by SEM. That compatibility between the fiber and LLDPE resin is improved on, which is essential reason of rigidity and toughness increase of the composites.
