摘　　要：针对聚苯硫醚存在韧性差的问题,通过热压成型工艺将玻璃纤维织物与聚苯硫醚树脂混合制备玻璃纤维增强聚苯硫醚复合材料。为获得较好的界面黏结性能,采用硅烷偶联剂KH560对玻璃纤维进行改性处理。借助扫描电子显微镜、摆锤冲击试验机、万能试验机等研究了不同质量分数硅烷偶联剂KH560处理对玻璃纤维表面形态及复合材料力学性能的影响。结果表明:当硅烷偶联剂KH560质量分数为2%时,玻璃纤维与聚苯硫醚基体结合得最好;经改性处理的玻璃纤维增强复合材料的拉伸强度、弯曲强度和冲击强度分别达到51.9 MPa、78 MPa和39.6 kJ/m^(2),相比于未处理前分别提升57.8%、51.8%和48.3%。To solve the problem of poor toughness of polyphenylene sulfide,glass fiber reinforced polyphenylene sulfide composites were prepared by mixing glass fiber fabrics with polyphenylene sulfide through hot pressing.In order to obtain better interfacial bonding properties,silane coupling agent KH560 was used to modify the surface of glass fiber.By means of scanning electron microscope,pendulum impact tester and universal tester,the changes of surface morphology of glass fiber treated with different concentrations of silane coupling agent KH560 and its effect on the mechanical properties of the composites were studied.The results show that when the mass fraction of the silane coupling agent KH560 is 2%,the glass fiber and the polyphenylene sulfide matrix achieves the best bonding,and the tensile strength,flexural strength and impact strength of the modified glass fiber reinforced composite reach 51.9 MPa,78 MPa and 39.6 kJ/m^(2) respectively,representing increases of 57.8%,51.8%and 48.3%compared with untreated.
