摘要/Abstract

摘要： 预浸料要求树脂基体和增强纤维具有良好的匹配性,为了提高芳纶纤维/环氧树脂预浸料的界面相容性,本文从芳纶纤维表面改性及增韧技术两个方面进行综述,讨论了芳纶纤维物理改性和化学改性方法的优缺点,分析了界面增韧及环氧树脂基体的不同增韧途径,重点介绍了聚氨酯/环氧树脂互穿网络体系。认为芳纶纤维的偶联剂表面处理和聚氨酯增韧环氧树脂相结合,是提高芳纶纤维/环氧树脂预浸料层间剪切强度的的可行途径。

Abstract: A good match of resin matrix and reinforced fibers was necessary for prepreg. Therefore, the surface modification of aramid fiber and the toughening of epoxy resin were summarized to improve the interface compatibility of aramid fiber/epoxy prepreg. The merits and demerits of the physical and chemical modification of surface of aramid fiber were discussed. Various toughening methods of interphase and epoxy resin were analyzed and PU(polyurethane)/EP(epoxy) IPN(interpenetrating polymer network) was highlighted. The combination of surface modification of aramid fiber with coupling agents and PU toughening epoxy resin was suggested to be a practicable approach to improve the interlaminar shear strength (ILSS) of aramid fiber/epoxy prepreg.

Key words: aramid fiber, prepreg, surface modification, PU, toughening
