摘　　要：玻璃纤维(GF)改性尼龙(PA)复合材料是一种高性能工程塑料,其应用范围十分广泛。对影响PA/GF复合材料性能的重要因素进行综述。阐述了GF与PA基体界面作用力、GF的直径、挤出机螺杆组合及GF与其他无机填料的协同作用对PA/GF复合材料性能的影响规律。结果表明,对GF进行有机化改性或在PA基体中添加其他改性剂能显著提升PA和GF界面作用力,从而提高PA/GF复合材料的力学性能。GF的直径越小,PA/GF复合材料的力学性能越好。螺杆组合对PA/GF复合材料中GF的长度和分散性具有重要影响,联合使用齿形盘、反向齿形盘与啮合块,制备的PA/GF复合材料性能更好。与单独采用GF改性的PA复合材料相比,当其他无机填料与GF协同使用时,PA/GF复合材料的力学性能较好。最后,对未来GF改性PA复合材料的研究方向进行了展望。Glass fiber(GF)modified nylon(PA)composite is a kind of high performance engineering plastics,which has a wide range of applications.Several important factors affecting the properties of PA/GF composite were reviewed.The influence of the interfacial force between GF and PA matrix,the diameter of GF,the combination of extruder screws and the synergistic effect of GF and other inorganic fillers on the performance of PA/GF composite are emphatically described.The results show that the interfacial force between PA and GF could be significantly improved by organic modification of GF or addition of other modifiers to PA matrix,resulting in the improvement of the mechanical properties of PA/GF composite.The smaller the diameter of GF,the better the mechanical properties of PA/GF composite.Screw combination has an important influence on the length and dispersion of GF in PA/GF composite.The performance of PA/GF composite is better when the tooth disc,reverse tooth disc and meshing block are used together.When other inorganic fillers are used together with GF,the mechanical properties of PA/GF composite are better than those of PA composite modified by GF alone.Finally,the future research direction of GF modified PA composite is prospected.
