Fatigue Fracture Properties Of Wood Plastic Composites

Fatigue fracture properties of wood plastic composites (WPC) were investigated.The material was based on a wood flour/polypropylene (PP) master batch,and prepared to be 30wt% and 50wt% wood flour contents by the addition of PP pellets.First,kneading temperature and screw speed of a uni-axial extrude...
