Friction performance of two-ply paper-based friction material containing carbon material

To exert excellent tribological characteristics of carbon material, a two-ply paper-based friction material was developed successfully by paper-making process. The friction performances of carbon face were investigated with an inertia friction tester. The torque curve of carbon face was ideal, the coefficient of static friction was tower than that of dynamic in 0.28 MPa, the friction coefficient of static and dynamic decreased with the braking pressure increasing. To the fiber face, the coefficient of dynamic friction of carbon face was more stable in cycle braking process, the wear rate was lower, and it was efficient to protect the couple plate not to be worn.
