Abstract

Influences of different coupling agent and ratio of modifier content on impact strength and various linear thermal expansion coefficients of composites were investigated in this paper. The results showed low impact strength was the major drawback of WPC in many end-use applications. The variation of impact strength of composites with coupling agents is caused by coupling agents. The different matrix and ratio of modifier content exerted different influences on the various linear thermal expansion coefficients of composites in three temperature zones. The reduction of the LTEC appear in HDPE/Pine composites was caused by adding filler and coupling agent.
