Wear properties of a glass fiber filled PTFE composite under oil lubricaton

The friction and wear behavior of a glass fiber filled PTFE composite was s tudied by rubbing it against a steel counterface at a load of 300-1000N and a velocity of 0.6, 1.0m/s under oil-lubrication. The friction coefficient and wear rate of the PTFE composite increase gradually and reach their peak values at about P=800N but decrease with increasing contact load. The wear rates of the PTFE composite under high contact load conditions are much lo wer than those of WJ2 and CAC603, These results were discussed from the vie wpoints of the surface temperature and the influence of fillings with MoS2 and glass-fibers, A result is that the tribological properties of the PTFE composite depend on the glass-fibers exposed to the worn surface.
