| 摘 要： | 采用石墨/ 二硫化钼填充改性聚苯酯/ 聚四氟乙烯复合材料, 研究了复合材料的力学性能和摩擦磨损性能。研究表明, 石墨和MoS2 的加入不仅能够很好地改善Ekonol/ PTFE 复合材料的力学性能, 使复合材料的拉伸强度、弯曲强度和硬度均有所提高, 而且还使Ekonol/ PTFE 复合材料的摩擦系数增加, 磨损体积减小, 耐磨性能显著提高。当Ekonol 含量为5 % , 石墨/ 二硫化钼总含量为8 %时, 拉伸强度、弯曲强度分别提高了31 %和41 % ,硬度值约提高了713 %。SEM 分析表明, Ekonol/ 石墨/ MoS2 / PTFE 复合材料的磨损主要以粘着磨损为主。

| Abstract: | The mechanics, friction and wear properties of graphite/MoS2 filled Ekonol/PTFE composites were studied. The result shows that the addition of graphite/MoS2 not only increases the mechanical properties of Ekonol/PTFE composites, but also causes the friction coefficient to increase, the wear volume to decrease, and the abrasive resistance to remarkably increase. When Ekonol and graphite/MoS2 mass fractions are 5% and 8%, the tensile strength and bend strength of composites increase 31% and 41%, and the hardness increases 7.3 % too. The wear mechanism of Ekonol/graphite/MoS2/PTFE composites is adhesive wear, as indicated by SEM analysis of the worn surface. |
