The influence of hot water degradation for friction and wear properties on the glass fiber mat reinforced vinylester composite materials containing the pitch based short carbon fiber fillers was invistigated. Moreover, the fractal was used to quantify the change in a frictional coefficient curve, and the relation between the cumulative wear volume and its fractal dimension was discussed. As a result, it became clear that there was no relation between the coefficient of friction and the immersing time and its coefficient was dependent on the exposure rate of carbon fiber on worn surface. And, the value of scratch hardness decreased and cumulative wear volume increased due to increasing the volume of carbon fiber fillers and the immersing time. It was also shown that the change in a frictional coefficient curve could be quantitatively evaluated by the fractal dimension. It was found that the fractal dimension and the cumulative wear volume were a proportional relation.
