EFFECTS OF MODIFIER ON MECHANICAL PROPERTIES OF WGFRP/PP COMPOSITES

Abstract

Abstract: Polypropylene matrix composites(WGFRP/PP)filled with the Waste Glass Fiber Reinforced Plastics(WGFRP)debris was prepared by the banburying and mould pressing. The influences of WGFRP powder modified with silane coupling agents KH550, the amount of Modified Propylene Polymer (MAPP), Polyolefin elastomer (POE) to WGFRP/PP composite performance were studied. The results show that composite performance was enhanced a little with WGFRP powder modified with KH550, for which the tensile strength and flexural strength were increased by 28.63% and 20.13% with MAPP, respectively. The breaking elongation and impact strength were improved by POE, showing an increase of 152.36%, 45.43%, respectively. The SEM images show that the interfacial adhesion between WGFRP and PP is good by using agents. It presented improved performance macroscopically.
