%X 在氟橡胶(FKM)/炭黑共混体系中加入聚四氟乙烯(PTFE)微粉，制备FKM/PTFE/炭黑复合材料，并对其性能进行研究。结果表明，采用PTFE微粉部分替代炭黑，硫化胶的拉伸强度、拉断伸长率及撕裂强度均明显增大，耐磨性能提高，压缩永久变形有所减小，脆性温度大大降低，但低温回弹性变差。FKM/PTFE/炭黑复合材料的热稳定性降低，在452 ℃出现FKM热质量损失峰后，在551 ℃又出现了PTFE热质量损失峰。;The FKM/PTFE/carbon black composites were prepared by adding PTFE powder into FKM/carbon black composites，and their properties were investigated. The results showed that，by  partly replacing carbon black with PTFE，the tensile strength，elongation at break and tear strength of FKM/PTFE/carbon black composites improved obviously，the abrasion resistance  increased，the compression set decreased and the brittle point reduced，but the low temperature resilience became poor.The thermal stability of FKM/PTFE/carbon black composites decreased， the thermal weight loss peak of FKM occured at 452 ℃，and that of PTFE was at 551 ℃
