With development of manufacturing industry, the bearing capacity and wear resistance of a single polymer material are not enough to meet different requirements. PEEK is a semi-crystalline aromatic thermoplastic engineering plastic, whose unique structure enables it to have excellent self-lubrication and other excellent properties ( Yan et al., 2020 Zhang et al., 2020 Hron et al., 2021). The surface friction static electricity of PEEK and CF/PEEK composites decreased with the increase of humidity. The wear rate of CF/PEEK composite changed slightly, which was significantly lower than that of PEEK, and the main wear mechanism was adhesive wear. The wear rate of PEEK decreased firstly and then increases, which reached the lowest of 3.09 × 10 −5 mm 3/Nm when the ambient humidity was 40%. The results showed that friction coefficient of PEEK and CF/PEEK composite changed slightly with increase of ambient humidity. The surface analysis and properties of the materials were measured by 3D profiler, scanning electron microscope, friction electrostatic tester. The effects of ambient humidity on the tribological properties, wear mechanism and antistatic properties of prepared materials were systematically studied. The friction experiments of prepared materials were carried out using UMT-2. Then PEEK and CF/PEEK composites were prepared at the optimum sintering temperature. The mechanical properties and microstructure characterization results showed that the pure PEEK prepared at 350 ☌ showed excellent friction and wear properties. In view of this, pure PEEK was prepared by vacuum hot pressing sintering technology at different sintering temperatures. Due to the high molding temperature, the molding method of ordinary plastics and cavity abrasives are difficult to meet the requirements. Polyether ether ketone (PEEK) is one of the representatives of special engineering plastics. 2National Engineering Laboratory for Bearing Tribology, Henan University of Science and Technology, Luoyang, China. ![]() 1School of Materials Science and Engineering, Henan University of Science and Technology, Luoyang, China.Xianjuan Pang 1,2, Shiwei Yue 1,2, Suling Huang 1,2, Jinmeng Xie 1,2, Shuai Wang 1,2, Yun Yue 1,2, Chenfei Song 1,2* and Dong Li 2 ![]()
