Abstract: In this work, tribological behaviors and PV limit of chopped carbon fiber, glass fibers and MoS₂ reinforced PTFE composites were. investigated. The experiment results revealed that single incorporation of MoS₂ could improve anti-wear property significantly under low velocity but shown a failure at 3 m/s. However, glass fibers deteriorated the wear resistance of the FIFE composite drastically as single filler. A synergistic effect was found for the combination of MoS₂ and glass fibers, which lead to the best tribological properties with the highest PV limits of 9.5 MPa m/s at 1 m/s and 15 MPa m/s at 2 m/s.
