Study on the tribological behavior of hybrid PTFE/cotton fabric composites filled with Sb2O3 and melamine cyanurate

The tribological behavior of the hybrid PTFE/cotton fabric composites filled with microsize Sb2O3 and melamine cyanurate (MCA) was investigated. It was found that the wear rate of the hybrid PTFE/cotton fabric composites decreased when Sb2O3 was used as the filler but increased with MCA filler. It was also observed that hybrid fillers (consists of Sb2O3 and MCA) had a wear reduction effect on the hybrid PTFE/cotton fabric composites at lower loads but increased the wear rate at higher loads. The wear behavior of the composites was explained in terms of the topography of worn surfaces and transfer film formed on the counterpart pin.
