Abstract: The rate of wear is calculated from the weight data of the wear debris and the ratio of wear to the total content of the reinforcement materials. The amount of material removed from the composite material is obtained, due to the relative movement of the material with the steel disc. The loss of lost weight from composite materials means a decrease in the rates of wear. For example, increasing the wear rate of the composite material not reinforced by the other reinforced, accompanied by a large increase in plastic deformation and break the sub-surface layers . The randomly distributed particles and carbon fibers act as impediments to the deformation of the substrate (epoxy+resole resin) during loading.
