To improve the friction performance of PEEK under mine conditions,PEEK/SiO2/CF-MoS2 composites were prepared with nano-silica (SiO2),molybdenum disulfide (MoS2) and short-cut carbon fiber (CF) as reinforcing fillers.The sliding and rolling tribological properties of PEEK/SiO2/CF-MoS2 composites under different conditions were explored by simulating the operation mode of roller and tank ears in mine environment,and its wear morphology and mechanism were analyzed.The results show that PEEK/SiO2/CF-MoS2 composites have good antifriction and wear resistance under different load.The friction coefficient and wear rate of composites are the lowest under the condition of water lubrication and sliding friction and under the condition of dry friction and rolling friction,and the wear mechanism is mainly abrasive wear.Compared with the polyurethane materials commonly used in mines,the tribological properties of PEEK/SiO2/CF-MoS2 composites are better.
