| 摘 要： | 采用冷压烧结方法制备Sm2O3增强聚四氟乙烯／混杂纤维复合材料，用AG-1型电子万能试验机和MM-200型摩擦磨损试验机分别评价了Sm2O3增强聚四氟乙烯／混杂纤维复合材料的力学性能和摩擦磨损性能，采用扫描电子显微镜观察其磨损表面形貌．结果表明：添加少量Sm2O3可以提高炭纤维和玻璃纤维混杂填充PTFE复合材料的力学性能和摩擦磨损性能，尤其对改善减摩效果尤为显著；加入1％Sm2O3可以使PTFE／15％CF／10％GF复合材料的拉伸强度、弯曲强度和硬度分别提高9．0％、5．1％和49．1％，摩擦系数降低22％，磨痕宽度降低5．4％，得到性能较为优良的耐磨材料．这是由于Sm2O3起到了润滑及阻止纤维和基体磨损作用的缘故．

| Abstract: | Effect of Sm2O3 on friction and wear properties of PTFE/hybride fiber composites have been investigated using an MM-200 wear tester. Addition of Sm2O3 improved the mechanical and friction and wear properties of PTFE/hybride fiber composites, especially improved greatly the friction reducing properties of composites. The tensile strength, bending strength and hardness of PTFE/15% CF/10% GF composites after adding 1% Sm2O3 increased 9. 0%, 5.1% and 49.1% respectively, while the friction coefficient and wear width decreased 22% and 5.4%. The lubrication of Sm2O3 helped in maintaining a lower friction coefficient, prevented matrix and fibers from abrasion, and increased wear resistance. |
