Tribological Behaviour of Polymer-Based Composite Reinforced with Molybdenum Disulphide

Abstract

The application of polymers and polymer-based composite increasing rapidly in industrial sector, due to its unique properties. In this study, the tribological behaviour of Poly-ether-ether-ketone (PEEK) and Polytetrafluoroethylene (PTFE) based composites with different ratio content of molybdenum disulphide (MoS2) is analysed experimentally. The tribological behaviour of these new developed polymeric materials has been observed with the help of pin-on-disc setup for different loading condition. From these observations, 3 wt% of MoS2 base composite turned out to be the best in tribological properties as compared to other variants of composites. The improvement in PTFE due to 3 wt% MoS2 is close to 90–100% in wear and 30–40% in friction, as compared to the PEEK value.
