摘要
综述了聚四氟乙烯(PTFE)无机材料填充改性中纤维填充改性,颗粒填充改性以及复合填充改性三大类的改性研究进展。介绍了不同无机填料对于PTFE复合材料的力学性能以及摩擦学性能的影响,包括摩擦因数、拉伸强度以及材料硬度等,发现铜(Cu)粉、二硫化钼(MoS2)以及玻璃纤维(GF)等无机填料成本较低且对PTFE的力学性能以及摩擦学性能改善较为明显,更能满足实际工程应用。最后,分析了国内外近年来研究中所存在的问题,并提出了解决方向。
This paper reviewed the development status of three modification methods for the PTFE composites filled with inorganic materials including fibers,granule and fiber-granule composite fillers.The effects of inorganic fillers on the mechanical and tribological properties of PTFE composites were discussed,which involved the friction coefficient,tensile strength and material hardness.It was founded that many of inorganic fillers such as copper powders,molybdenum disulfide and glass fibers had a lower cost and a good modification effect on the improvement of mechanical properties and tribological properties of PTFE,and these fillers were more suitable for practical engineering applications.Moreover,the problems existed in the foreign and domestic researches in recent years were analyzed,and a solution direction was proposed.
