The tribological properties of Kevlar pulp reinforced friction material in the braking condition were investigated by means of simulating tests on a pin on disc friction and wear tester. As the results, the friction coefficient decreases with increase in the sliding velocity, but the wear rate of the friction material increases and the tribological properties of the tribo system are insensitive to load. With increase in the Kevlar pulp content in the composite friction material, the wear rate of the friction material decreases obviously. The friction coefficient of the tribo system, however, keeps almost unchanged. The inclusion of Kevlar pulp in the composite friction material helps to improve the friction stability and wear resistance of the friction material.
