[0002] Friction material is a material used for vehicle and winter mechanical braking and transmission. Its quality directly affects the reliability of mechanical equipment and the safety of operators. It mainly includes brake pads and clutch surfaces. Brake pads are used for Braking, clutch face is used for transmission, clutch face transmits force, brake pad absorbs kinetic energy, and ensures the safe operation of the car. Friction material is a very critical material; phenolic and aldehyde polycondensation products are collectively called phenolic resin, which has excellent Mechanical, heat resistance, cold resistance, electrical insulation, dimensional stability, molding processing and flame retardancy, have a wide range of uses, the weak link of the phenolic resin structure is that the phenolic hydroxyl and methylene are easy to oxidize, heat resistance Affected, with the continuous development of industry, especially the development of various automobile use conditions, higher requirements are put forward for high-performance wear-resistant materials. Pure phenolic resin is used as a friction material with poor toughness and insufficient heat resistance. The base material of brake pads cannot meet the demand
