Abstract
- An anti-wear filler of molybdenum disulfide (MoS 2) coated chopped carbon fiber (SCF) was synthesized by hydrothermal method and blended with nano-SiO 2 to enhance the tribological properties of PEEK composites materials. The results show that the SCF-MoS 2 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/SiO 2 /SCF-MoS 2 composites are increased by 62.04% and 26.49% respectively. The friction coefficient and wear rate of PEEK/SiO 2 /SCF-MoS 2 composites are reduced by 31.43% and 79.18% respectively. In addition, it also shows good tribological properties in the simulation coal mine environment. [ABSTRACT FROM AUTHOR]
