ZnO nanoparticles were incorporated into phenolic resin and the effect of the ZnO content on tribological properties of hybrid polytetrafluoroethylene (PTFE)/Kevlar fabric/phenolic composite was investigated. Fabric composite filled with 5 wt.% ZnO nanoparticles sliding against steel, copper, or aluminum was investigated in detail. Friction and wear tests showed that fabric composite/steel exhibited lower friction coefficient and wear rate with varied loads and speeds. It is believed that the coherent transfer film and tribochemical reactions involved in fabric composite/steel contributed to the reduced friction coefficient and wear rate of the fabric composite.
