	Abstract

3D braided glass fiber reinforced visible-light-cured resin composites (denoted as G_3D/EEPE) were prepared by impregnation plus light-cured technique, and their tribological properties were studied in this work. It was found that the coefficient of friction and the specific wear rate of the G_3D/EEPE composites decreased with increasing V_f. Beyond a V_f of 32%, however, a slight increase in the specific wear rate of the G_3D/EEPE composites was found. The decreased friction coefficient and increased specific wear rate were observed in the G_3D/EEPE composites with increasing normal load regardless of velocity. The silane coupling treatment effectively improved the wear resistance of the G_3D/EEPE composites. Though the G_3D/EEPE composites showed lower friction coefficient and specific wear rate at lubricated condition than at dry contact, the similar adhesive wear mechanism was observed under two conditions.
