Abstract：Heavy-duty and special vehicle transmissions generally use friction plates based on copper-based powder
metallurgical materials. With the development of the transmission to high speed, high torque, heavy load, etc.,
the problems of inadequate performance of traditional friction plates are gradually leaking out, such as friction layer
peeling, core plate fracture. Aiming at the problems that are becoming increasingly evident in copper-based friction
plates, the development process of friction discs and the current application status of copper-based friction
discs are analyzed, their composition and material composition are introduced, and the common failure forms and
requirements of friction discs are explained. Further, the targeted strategies are proposed in terms of composition
design, manufacturing process, structural design, post-treatment strengthening, and so on. It is pointed out that the
optimization of multi-process coupling and the resrarch of new environmentally friendly composite friction plates
will be an important direction for the development of friction plates.
