Around the enhancing of friction coefficient of the friction materials at high temperature, the thermal stability of the molybdenum-modifying phenolic resin has been determined through DTA and TC. The process line and process conditions of the friction materials are determined. The friction materials have been made from this resin. At the same time, the friction coefficient of the friction materials have also been tested. The results show that this resin has good thermal stability, the decomposing temperatu...
