| 摘 要： | 以竹粉和聚丙烯粉料为原料,马来酸酐接枝聚丙烯为偶联剂,通过注塑成型制备了竹塑复合材料.研究了不同粒径竹粉对复合材料力学性能的影响.结果表明:不同粒径的竹粉对复合材料拉伸性能、弯曲性能及冲击强度均有显著的影响.竹粉粒径在40～120目时,随着粒径的减小,复合材料的拉伸强度、弯曲强度,以及缺口冲击强度呈逐渐减小的趋势.当粒径达到200目时,复合材料的拉伸强度、弯曲强度及缺口冲击强度却有所增大.竹粉粒径为20目时,复合材料的拉伸强度、弯曲强度以及缺口冲击强度均比40目的要低.大粒径竹粉(40目)与小粒径竹粉(200目)填充的复合材料表现出的不同力学性能,可能与竹粉与基体塑料界面结合、纤维形态、表面粗糙度以及内部空隙状况不同有关.
