中文摘要：

采用环氧树脂、固体润滑剂及碳纤维布／聚四氟乙烯（CF／PTFE）混编织物来制备复合材料，测试复合材料在常温下的压缩强度、摩擦系数并对其破坏机理进行分析。结果表明，CF增强扇润滑复合材料的压缩强度可达503．25MPa。CF／PTFE混编增强自润滑复合材料压缩强度大幅下降。质量分数20％PTFE混编增强自润滑复合材料压缩强度为243．89MPa，相比CF增强自润滑复合材料下降51．65％。质量分数20%PTFE混编增强自润滑复合材料摩擦系数较CF增强自润滑复合材料摩擦系数降低了32．35％。

英文摘要：

Composites were prepard by using epoxy,solid lubricant and carbon fabric/ polytetrafluoroethylene（CF/PTFE） hybrid fabric. The compressive strength at room tem- perature and friction coefficient of the composites were tested, and its tailure mechanism was analyzed. The results show that the compressive strength of CF reinforced self-lubrica- ting composites is 503.25 MPa. The compressive strength of CF/PTEF hybrid fabric rein- forced self-lubricating composites decreases significantly. The compressive strength of 20% PTFE hybrid fabric reinforced self-lubricating composites is 243.89 MPa which reduces by 51.65% compared with that of the CF reinforced self-lubricating composites. The friction coefficient of 20% PTFE hybrid fabric reinforced self-lubricating composites reduces by 32.35% compared with that of the CF reinforced self-lubricating composites.
