STUDY OF COUPLING AGENT FOR WOOD-PLASTIC COMPOSITE

WPC with coupling agent has better mechanical properties such as flexural modulus than that without coupling agent. In case of impact strength, that of WPC with coupling agent decreases compared with that of WPC without coupling agent. Between wood fiber and resin, interaction force of WPC without coupling agent is small. When WPC is impacted,
