Experimental Investigation of Injection Molding of Wood/Plastics Composites

In this article, injection processing of wood flour/PP composite and the effects of processing parameters on its mechanical properties are investigated. Injection pressure and pressure holding time were systematically chosen as the critical processing parameters. The results of this research work indicate that increasing injection pressure and holding time has considerable effect on final modulus of elasticity, noticeable decreasing effect on elongation, and insignificant effect on tensile strength.
