Tribological Behaviors of Hybrid PTFE/Kevlar Fabric Composite with Fine Serpentine Particle Under Dry Sliding Condition
This paper presents a hybrid PTFE/Kevlar fabric composite filled with fine serpentine particles that exhibits remarkablely improved wear resistance. The friction and wear properties of such composites filled with different serpentine contents were evaluated on a MMU-5G friction and
wear tester. It was observed that the anti-friction property of all composites was weakly dependent on the serpentine content. The friction coefficient was stable and varied slightly during the steady-state sliding, while the anti-wear properties were significantly improved with the incorporation
of serpentine in all composites. When the mass fraction of serpentine particle was 0.5%, the composite showed the best wear resistance.
