摘　　要：用聚丙烯(PP)、高密度聚乙烯(HDPE)共混制备竹木塑复合材料,研究其对复合材料力学性能和微观结构的影响,同时对比竹粉与木粉对材料性能的影响。结果表明:竹塑复合材料的拉伸强度较高;加入一定量的高密度聚乙烯可以提高聚丙烯/竹粉复合材料的冲击和弯曲强度;竹粉与塑料的相容性比木粉好,木塑复合材料的主要破坏形式是木粉与塑料的脱粘。Bamboo/wood-plastic composite was prepared by the mixing of PP and HDPE,the mechanical properties and microstructure of composite was studied. The deferent effect between bamboo and wood also be compared. The results showed that bamboo-plastic composite had better tensile strength than wood-plastic composite. The impact strength and bending strength of bamboo-PP composite could be improved by adding HDPE. Bamboo had better compatibility with plastic than wood. For wood-plastic composite,the main failure mode was debonding between wood flour and plastic.
