Description

technical field [0001] The invention relates to a novel friction material for brake pads. Background technique [0002] Friction material is a component material used in power machinery that relies on friction to perform braking and transmission functions. It mainly includes brake linings (brake pads) and clutch facings (clutch plates). Brake pads are used for braking and clutch plates are used for transmission. Any mechanical equipment and various moving vehicles must have braking or transmission devices. Friction material is a critical component on this braking or transmission. Its main function is to absorb or transmit power through friction, and they enable mechanical equipment and various motor vehicles to work safely and reliably. Therefore, the friction material is a widely used and critical material. [0003] However, the existing friction materials used for brake pads are prone to thermal decomposition, and after a long time of use, the wear resistance decrease...
