Research advances of carbon fiber reinforced paper-based friction materials

Paper-based friction material is a kind of porous wet friction materials which has been widely used in wet clutches and brakes of vehicles for its good friction properties. Due to the advantages of stable friction coefficient, excellent abrasion resistance, high mechanical strength and good chemical stability, carbon fiber has been widely used in various types of composite materials as reinforcement. And it will be the ideal reinforced fiber for paper- based friction materials. This paper briefly introduces the development of carbon fiber rein- forced paper based friction materials at home and abroad, and mainly focuses on the compo- nent, tribology properties and mechanism of the friction materials. Finally the development tendency of carbon fiber reinforced paper-based friction material was presented.
