Abstract

The invention discloses a novel brake pad wear-resistant material which comprises the following materials in parts by weight: 30-40 parts of aramid fiber, 10-30 parts of modified phenolic resin, 7-15 parts of aluminum powder, 1-5 parts of zircon, 3-5 parts of lead sulfide, 20-30 parts of calcium fluoride, 1-10 parts of artificial graphite, and 5-10 parts of sepiolite fiber. The novel frictional material for the brake pad has the advantages of being stable in friction coefficient, low in wear rate, and good in strength, as well as the advantages of being better in impact strength, low in product density, low in hardness, low in braking noise, incapable of damaging a braking dual and the like, and the service life can be greatly prolonged.

Description

technical field [0001] The invention relates to a novel wear-resistant 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. However, the existing friction materials used for brake pads are prone to thermal decomposition, and after a long time of use, the wear resistance decreases, ...
