Abstract
Friction and wear behaviors of MoS2 and PTFE-modified carbon fabric composites were studied by using an Xuanwu-III high temperature friction and wear tester. Effects of MoS2 content and test temperature on the tribological properties of carbon fabric composites were studied also. Worn surfaces and counterpart worn surface were analyzed by using a JSM-5600LV scanning electron microscopy (SEM) equipped with an energy dispersive X-ray analyzer (EDXA). It is found that friction-reducing and anti-wear properties of carbon fabric composites can be greatly improved by filling MoS2, but PTFE as filler reinforced carbon fabric composites is not beneficial for enhancing their anti-wear and reducing-friction ability. When content of MoS2 is 5%-15%, MoS2 as filler can obviously reduce friction coefficient of carbon fabric composites. When content of MoS2 is 10%, carbon fabric composites exhibit best tribological properties. Friction coefficient and wear rate of MoS2-modified carbon fabric composites is lower than unmodified carbon fabric composites at different test temperatures. When test temperature rises to 240°C, wear rate of carbon fabric composites increases rapidly, but wear rate of MoS2-modified carbon fabric composites can be reduced 35% compared to that of unmodified carbon fabric composite.
