摘　　要：以丙烯腈-丁二烯-苯乙烯共聚物(ABS)及短玻璃纤维(SGF)为原料,以苯乙烯-马来酸酐共聚物(SMA)和环氧树脂(EP)为界面相容剂,制备了SGF/SMA-EP-ABS复合材料。用扫描电镜(SEM)、动态力学热分析(DMTA)等研究了界面相容剂对SGF增强ABS复合材料力学性能及界面粘结性能的影响。结果表明:加入SMA或EP,SGF增强ABS复合材料的力学性能明显提高;SMA与EP同时加入具有明显的协同效果,使复合材料的性能更为优越。当SGF加入质量分数为30%时,SGF/SMA-EP-ABS复合材料的拉伸强度、弯曲强度、冲击强度较未添加界面相容剂时分别提高了56%、42%、79%。SEM和DMTA测试表明,加入SMA和环氧树脂后,SGF与ABS基体之间的界面粘结性能得到很大改善。The short glass fiber（SGF） reinforced composites were prepared by the injection molding using acrylonitrile-butadiene-styrene copolymer（ABS） and the short glass fibers as the raw materials,styrene-maleic anhydride copolymer（SMA） and epoxy resin（EP） as the compatibilizer.The effects of compatibilizer on the mechanical properties and interfacial adhesion of the composites were investigated using SEM,dynamic mechanical analysis（DMTA） and mechanical measurement.It was found that the mechanical properties of SGF/ABS composites could be improved by the incorporation of SMA or EP.Compared to the composites without compatibilizer,the tensile strength,flexural strength and impact strength could be improved by 56%,42% and 79% respectively for SGF/EP-SMA-ABS composites with 30% mass fraction of short glass fibers.SEM and DMTA reveal that the incorporation of SMA and EP could introduce great improvement to the composites.
