摘要: 采用混编法制备碳纤维(CF)/聚苯硫醚(PPS)混编织物,通过模压成型制备出连续碳纤维增强聚苯硫醚复合板材。研究铺层层数、热压温度、热压时间、树脂含量和处理混编织物的硅烷偶联剂种类对复合板材力学性能的影响,采用万能材料试验机、扫描电子显微镜、SEM-EDS等手段对碳纤维和复合材料层压板进行表征。结果表明碳纤维增强聚苯硫醚复合板材的最佳工艺条件为:铺层层数为20层,热压温度为330 ℃,热压时间为30 min,树脂质量分数为50.2%;使用硅烷偶联剂KH560处理后,复合板材力学性能显著提高,其拉伸强度和弯曲强度分别为920.1 MPa、890.6 MPa。

Abstract: CF/PPS was prepared by blending method,and continuous carbon fiber reinforced polyphenylene sulfide composite laminates were prepared by moulding process. The effects of layers, hot pressing temperature, hot pressing time, resin content and silane coupling agents on the mechanical properties of composite laminates were studied. Carbon fibers and composite laminates were characterized by universal material testing machine, scanning electron microscopy and SEM-EDS. The results show that the optimum technological conditions of carbon fiber reinforced polyphenylene sulfide composite laminates are as follows: the number of layers is 20, the hot pressing temperature is 330 ℃, the hot pressing time is 30 min, and the resin mass fraction is 50.2%. The mechanical properties of composite laminates are significantly improved after being treated with silane coupling agent KH560, and their tensile strength and flexural strength are 920.1 MPa and 890.6 MPa, respectively.

Key words: polyphenylene sulfide, thermoplastic composites, mixed weave fabric, silane coupling agent
