摘　　要：采用高效无卤阻燃剂CJ-1002、玻璃纤维、马来酸酐接枝乙烯辛烯共聚弹性体(POE-g-MAH)对聚对苯二甲酸丁二醇酯(PBT)进行阻燃及力学改性,研究了加工工艺对复合材料性能的影响。实验表明,PBT、阻燃剂、玻纤、POE-g-MAH的质量比为48/18/30/4时,复合材料在阻燃级别达到V-0的同时,拉伸强度、弯曲强度以及缺口冲击强度较改性前都有比较大的提升。High-efficiency halogen-free flame retardant CJ-1002, glass fiber, ethylene-octene copolymer grafted with maleic anhydride （POE-g-MAH） was used to modify the mechanical property and flame-retardant of polybutylene terephthalate （ PBT）, the effect of the technical processing on the properties of composite was studied. The results showed when the mass ratio of PBT, flame retardant, glass fiber, and POE-g-MAH was 48/18/30/4, the composite materials reached flame-retardant level of V-0, at the same time, comparing with pre-modified samples, the tensile strength, bending strength and notched impact strength increased obviously.
