摘　　要：针对超高相对分子质量聚乙烯(UHMWPE)纤维表面光滑,易出现纤维脱胶和树脂基团开裂的问题,提出用AgNO_(3)和K2S_(2)O_(8)对纤维进行改性,在纤维表面引入环氧基,以提高复合材料的整体性能。最后,对氧化改性后纤维增强复合材料的界面剪切强度、横向和纵向拉伸强度等进行分析。结果表明,引入环氧基的纤维增强复合材料,界面剪切强度、纵向、横向拉伸强度达到3.25MPa、104.03MPa和48MPa,表现出良好的性能。In order to solve the problems of smooth surface,easy to degumming and resin group cracking of ultra-high molecular weight polyethylene(UHMWPE)fiber,the AgNO_(3) and K_(2)S_(2)O_(8) are used to modify the fiber,and the epoxy group is introduced into the fiber surface to improve the overall performance of the composite.Finally,the interfacial shear strength,transverse and longitudinal tensile strength of the oxidation modified fiber reinforced composites are analyzed.The results show that the fiber reinforced composites with the epoxy group exhibit good properties,its interfacial shear strength,longitudinal tensile strength and transverse tensile strength is 3.25 MPa,104.03 MPa and 48 MPa respectively.
