Problems solved by technology

[0002] As we all know, automobile brake pads are important and key components for the normal and safe operation of automobiles. Existing automobile brake pads mainly include friction layer, steel back, noise reduction sheet, and alarm card through production, processing and assembly. The friction layer is different due to different materials. It is divided into asbestos brake pads, powder metallurgy brake pads and semi-metal brake pads. Asbestos brake pads have poor wear resistance, and asbestos is a high carcinogen and easy to pollute the environment. It has been gradually eliminated in recent years.
Metal brake pads and semi-metal brake pads have poor thermal stability. When the friction generates high temperature, their friction force decreases, which directly affects the braking performance. Also, metal and semi-metal brake pads have high hardness, which will cause the wear of the dual material brake disc. Large, the brake disc will be marked with grooves (grooves), and harsh metal noise will be produced when braking, which will affect the environment and the comfort of drivers and passengers
