Abstract
An anti-wear filler of molybdenum disulfide (MoS2) coated chopped carbon fiber (SCF) was synthesized by hydrothermal method and blended with nano-SiO2 to enhance the tribological properties of PEEK composites materials. The results show that the SCF-MoS2 has stronger adhesion with the PEEK matrix, which is more conducive to the internal stress transfer of PEEK composites. Compared with pure PEEK, the elastic modulus and tensile strength of PEEK/SiO2/SCF-MoS2 composites are increased by 62.04% and 26.49% respectively. The friction coefficient and wear rate of PEEK/SiO2/SCF-MoS2 composites are reduced by 31.43% and 79.18% respectively. In addition, it also shows good tribological properties in the simulation coal mine environment.
