Effects of glass fiber and molybdenum disulfide on tribological behaviors and PV limit of chopped carbon fiber reinforced Polytetrafluoroethylene composites

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 PTFE 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.
