Problems solved by technology

[0002] As we all know, automobile disc brakes are braked by the friction between the friction material on the friction plate and the surface of the brake disc under the action of external force, and the friction material will wear and tear. When the wear reaches a certain level, the friction plate will Thinning, so the friction plate should be replaced regularly, otherwise it will affect the performance of the car
[0003] At present, semi-metallic friction materials are added to the preparation of friction plates, which overcomes the shortcomings of asbestos friction materials, such as serious thermal degradation at high temperatures and easy cracking on the friction surface. For the processing of semi-metallic friction plates, only traditional sintering molding is used, which is wear-resistant. The performance gradually declines after a long time of use, and new friction linings need to be replaced, resulting in a low service life of the friction linings
