Abstract

The mechanical properties of high-density polyethylene (PE-HD)/woodflour composites treated with different interfacial compatibilizers were investigated. Results show that all interfacial compatibilizers increase the mechanical properties of PE-HD/woodflour composites. MAPE gives the greatest improvement in tensile, flexural strength; the composites' strength reaches maximum level with 10% MAPE content; EPDM-MA has a positive effect on impact strength; and EVA-MA enhances the properties of the composites; addition of SBS shows no obvious effect on interfacial adhesion; while addition of MAPE improves the impact strength of the composites obviously when used together with elastomer SBS, it may attribute to the synergism between MAPE and SBS, therefore, to form a flexible interphase around the woodflour particles giving the composites better impact strength.
