摘要
在MM-200型摩擦磨损试验机上，对3K炭布叠层结构的炭，炭（C/C）复合材料进行低能条件下的摩擦磨损实验，用扫描电子显微镜对其磨损表面形貌进行观察分析。结果表明：在干摩擦条件下，随转速增加，复合材料的摩擦系数降低，磨损量增大。随载荷增加，复合材料的摩擦系数降低，磨损量增大。摩擦初始时主要磨损机理为磨粒磨损和粘着磨损，润滑膜产生后主要磨损机理为疲劳磨损。炭，炭复合材料在低能条件下的磨损是正常磨损，其摩擦系数在0．1～0．2，温度在0～100℃之间。
The tribological propoties of C/C composites which weaved in 3K colth composites have been studied on MM-200 tribelngical machine, and the microstructure of the friction surface was observed. The experiments showed that the coefficient of friction has been increased when the velocity improved while the wear rate has improved at the same time. The friction coefficient has been decreased when the load improved while the wear rate has improved at the same time. The results indicate that the tribelogical behaviors were abrasive wear and adhesion wear at the beginning and the tribological behavior were fatigue wear when the fricton film have appeared. According to the result, it was normal wear of C/C composites on low energy while the friction coefficient changed between 0.1 - 0.2 and the temperature on friction surface was 0 ～100℃.
