Abstract

In this work, the PLA/PBS/straw powder wood-plastic composite were fabricated by injection molding process. Special attention was paid to the effects of different parameters of injection molding process on the mechanical properties of the wood-plastic composite. The optimum injection molding process parameters of wood - plastic composites were determined by orthogonal experiment. According to the optimal injection molding process parameters, biodegradable wood-plastic composites filled with different compatibilizers were produced. The effects of MAPLA, silane and combination treatment on the interface compatibility and mechanical properties of the wood-plastic composite were investigated by scanning electron microscope and mechanical properties test. The results showed that the combination of the two compatibilizer treatments can improve the interface compatibility of wood-plastic composites, but the improvement of it mechanical properties is not obvious. The mechanical properties of wood-plastic composites were optimiz when the content of MAPLA was less than 5%.
