Abstract Hybrid PTFE/Kevlar fabric was surface‐modified by air plasma to improve the adhesion to phenolic resin. The tribological properties of fabric composite with or without plasma‐treated hybrid PTFE/Kevlar fabric were investigated in detail. Friction and wear tests showed that friction‐reducing and antiwear ability of hybrid PTFE/Kevlar fabric composite were remarkably improved after plasma treatment. Scanning electron microscopy and X‐ray photoelectron spectroscopy results indicated that the fiber surfaces were etched and the contents of oxygen and nitrogen increased after plasma treatment, which was favorable for improved fiber/resin bonding strength. The enhancement contributed to the improved tribological properties of hybrid PTFE/Kevlar fabric composite after plasma treatment. © 2009 Wiley Periodicals, Inc. J Appl Polym Sci, 2009
