摘要
以三维编织超高分子量聚乙烯(PE–UHMW)纤维为增强体,环氧树脂(EP)为基体,通过树脂传递模塑工艺制备了EP/三维编织PE–UHMW纤维复合材料,研究了纤维含量和载荷对复合材料摩擦系数与磨损率的影响,并采用扫描电子显微镜对复合材料磨损表面进行了分析。结果表明,随着纤维体积含量的增加,复合材料的摩擦系数和磨损率逐渐减小;随着载荷的增大,复合材料的摩擦系数逐渐减小,但磨损率增大;复合材料的磨损机制以粘着磨损为主。
3D braided polyethylene, ultra-high molecular weight(PE-UHMW) fiber reinforced epoxy(EP) resin composites were prepared using resin transfer molding process.The effects of load and fiber volume content on friction and wear characteristics of the composites were investigated on a friction and wear tester, and the microscopic wear surface was analyzed using scanning electron microscopy.The results show that the friction coefficient and wear rate decrease with fiber volume content increasing ; and with the increase of load, the friction coefficient of composites decreases, however, the wear rate of composites increases.The wear mechanisms of the EP/3D braided PE-UHMW fiber composites are mainly adhesive wear.
