摘　　要：为优化聚醚醚酮(PEEK)材料的综合力学性能,制备了含有不同比例的碳纤维(CF)和玻璃纤维(GF)的复合PEEK丝材。采用GB/T 1447-2005纤维增强塑料拉伸性能试验方法对含有不同组分的复合丝材力学性能进行测试,并使用扫描电子显微镜(SEM)对其微观结构进行研究。结果表明:PEEK/CF复合丝材的强度随CF含量增加而增强。PEEK/GF复合丝材强度也随GF含量增加而增强,添加10%GF的复合丝材强度相较于纯PEEK丝材提升明显,但随着GF含量继续增加,整体强度提升缓慢。In order to optimize the comprehensive mechanical properties of polyetheretherketone(PEEK)materials,researchers prepared composite PEEK filaments containing different proportions of carbon fiber(CF)and glass fiber(GF).Researchers used the GB/T 1447-2005 fiber-reinforced plastic tensile performance test method to test the mechanical properties of composite filaments containing different components,and studied their microstructure using scanning electron microscopy(SEM).The results indicate that the strength of PEEK/CF composite wire increases with the increase of CF content.The strength of PEEK/GF composite wire also increases with the increase of GF content.The strength of composite wire with 10%GF added is significantly higher than that of pure PEEK wire,but the overall strength improvement is slow as the GF content continues to increase.
