摘　　要：采用磷酸酯偶联剂对芳纶纤维表面进行接枝改性,研究了实验条件和纤维含量对芳纶纤维增强聚丙烯(PP)复合材料力学性能的影响,并用电子扫描显微镜观察了PP复合材料的微观形态结构。结果表明:磷酸酯偶联剂成功接枝到芳纶纤维表面上,使芳纶纤维和PP的界面黏结性能得以明显改善。芳纶纤维可以显著地提高PP复合材料的力学性能当,其含量为20%时复,合材料的综合性能最优。Aramid fibers were modified by using phosphate coupling agent. The effect of experimental conditions and fiber loading on mechanical properties of polypropylene/aramid fibers （PP/AF） composites was investigated and the microstructure of composites was also observed by scanning electron microscopy. The results show that： phosphate coupling agent is successfully grafted on the surface of aramid fibers, which considerably improves the interfacial adhesion between aramid fibers and polypropylene. Moreover, the mechanical properties of reinforced PP composites are significantly enhanced with the best AF loading of 20%.
