Study on the preparation and properties of paper-based friction material reinforced by carbon fiber

In order to improve the fiction performance of asbestos-free paper based friction materials, a new type of friction materials reinforced by shorter carbon fiber was prepared by paper-making procession. The heat resistance of the material is exercised with TG-DTA analysis; the relation between dynamic friction coefficient and rotational velocity of separator plate and friction distance is executed with MHK-500 type wear tester. Result shown that the dynamic friction coefficient of new friction material is in the range of 0.136-0.149, as high as traditional asbestos-rein-forced paper type friction materials, and the heat fade of friction coefficient with friction distance is couldn't found. The new type friction material is an ideal paper type friction material.
