| 摘 要： | 采用人造海绵为模板,通过浸渍酚醛树脂和环氧树脂,制备了具有海绵构造的碳/环氧树脂网络互穿复合材料。并研究了该复合材料的微观形貌及摩擦磨损性能。结果发现人造海绵的网络状构造很好地复制到了复合材料中。与环氧树脂相比,复合材料的磨损率和摩擦系数都降低了。复合材料中的网状碳限制了环氧树脂基体的应变和回弹能力,使其摩擦系数变动范围变小。显示出此类复合材料具有更加稳定的摩擦磨损性能。

| Abstract: | Artificial sponges were used as templates,by infiltrating phenolic resin and epoxy resin,polymer matrix composites with sponge-like network were made.Microstructures and friction wear properties were studied on the composites.The wear rates of the composites are shown to be lower than that of the epoxy resin.The composites also exhibit a lower coefficient of friction compared with epoxy resin,and the coefficients of friction of the composites changed in a more narrow range than that of the epoxy resin.These results demonstrate a more stable friction state for this type of composite. |
