摘要
在聚四氟乙烯(PTFE)中分别填充碳纤维(CF)、玻璃纤维(GF)及这两种纤维不同配比的混杂纤维(HF),制备了具有不同力学性能和摩擦磨损性能的PTFE基复合材料。探讨了填料组成对复合材料硬度和干摩擦条件下摩擦磨损性能的影响,并研究了PTFE基复合材料磨损表面的形貌学。结果表明,适量填充CF和GF均可提高PTFE的摩擦磨损性能,CF比GF效果更为显著;CF和GF的混杂纤维填充PTFE复合材料,表现出一定的协同性,比填充单种纤维,其效果更显著。
Polytetrafluoroethylene （PTFE） composites filled with carbon fiber （CF）, glass fiber （GF） and the hybrid fiber （HF） of different compounding ratios of CF and GF respectively were pepared. The effects of the compositions of the filler on the hardness and tribological properties of the composites under dry condition were studied. The morphology of the worn composite surfaces were examined by means of SEM. The results showed that proper filling with CF or GF could improve the hardness and the wear resistance of the composite, and the filling with CF was better. The filling with HF had synergistic result, which was better than that with a single fiber.
