▎ 摘　　要

Graphene and polystyrene functionalized graphene (PS-graphene) had been synthesized, and were employed as fillers to improve the anti-wear property and load-carrying capacity of Nomex fabric/phenolic composites. Pin-on-disk type wear tests show that the friction coefficients and wear rates for both graphene and PS-graphene filled fabric/phenolic composites were reduced, when compared with unfilled fabric composite. Moreover, it was found that the 2 wt% PS-graphene filled Nomex fabric/phenolic composites exhibited the optimal tribological properties. The enhancement on the wear property of graphene and PS-graphene filled Nomex fabric composite was mainly due to the self-lubrication of graphene and the easy-formed transfer film on the counterpart pin. We also investigated the effect of filler content, applied load, and sliding speed on the tribological properties of the Nomex fabric/phenolic composites. (C) 2013 Elsevier Ltd. All rights reserved.
