| Abstract: | The relationship between reinforcing fiber content and friction coefficient, wear rate, impact stress and hardness of automotive friction materials was studied with D MS and MM 1000 testers and SEM as well. It is found that the impact strength,bending strength and hardness increase as the fiber content increases. The friction coefficient and wear rate are closely dependent on the reinforcing fiber content. When the volume fraction of fiber is 10%, the friction material has high and stable friction coefficient, low wear rate and acceptable impact strength and hardness. Moreover, the wear mechanisms of the friction materials are also related with the volume fraction of the reinforcing fiber. |
