The effect of abrasive wear at frictional sliding interface on shear frictional resistance in fiber-reinforced composite has been studied using W fiber-reinforced epoxy model composite. The interface shear frictional resistance decrease with the increase of fiber-matrix relative interface sliding during pushout test. Observation of the matrix surface after the test shows that abrasive wear occurs on the matrix surface caused by the rough fiber during fiber sliding, and this wear results in the decrease of the shear frictional resistance. The coefficient of friction is separated into the contribution of wear and adhesion using a simple analysis. The contribution of wear increase with the increase of fiber surface roughness, and the total coefficient of friction decreases significantly with the proceeding of interface sliding due to the reduction of the wear contribution part.
