Brake pad wear resistance
The friction plate of the brake is in direct contact with the brake disc. During braking, the friction generated by the relative movement of the two can generate braking torque. The working conditions of the friction plate are very harsh, so in order to ensure reliable operation, it must achieve a very important The requirement is the wear resistance of the brake friction plate.
The wear resistance of the brake friction pad material is a reflection of its service life and is also an important technical and economic indicator to measure the durability of the brake friction pad material. The better the wear resistance, the longer its service life. However, the wear of the brake friction pad material during operation is mainly caused by the shear force generated by the contact surface of the brake friction pad.
Operating temperature is an important factor affecting the amount of wear. When the surface temperature of the material reaches the thermal decomposition temperature range of the organic binder, the organic binder such as rubber and resin will decompose, carbonize and lose weight. As the temperature increases, this phenomenon intensifies, the bonding effect decreases, and the amount of wear increases sharply, which is called "thermal wear".
Selecting appropriate anti-friction fillers and resins and rubbers with good heat resistance can effectively reduce the working wear of the material, especially thermal wear, and extend its service life.
