Abstract

The invention discloses a friction material which comprises a metal material, a bonding material, an abrasive material, a fiber reinforced material, a friction increasing material, a friction reducing material, a function reinforced material and other fillers. According to the invention, the powder metallurgy technology is utilized to combine the advantages of the iron-based friction material and the copper-based friction material, then the combination material, the abrasive material, the friction increasing material, the friction reducing material, the function reinforcing material, the fiber reinforcing material and other fillers are reasonably matched, and all the components are kept in the material in a mechanical combination manner, so that the whole friction material with certain mechanical properties is formed. The heat resistance of the friction material is improved, the components of low-melting-point metal are reduced, the content of metal with high heat conductivity is increased, the friction coefficient stability of the friction material can be improved, the heat fading phenomenon caused by sharp temperature rise of the friction material due to emergency braking or continuous downhill is improved, and the service life of the friction material is prolonged. Under the condition that the moderate and stable friction coefficient is ensured, the excellent characteristics of noise reduction, heat resistance and small dual damage are also realized.

Description

technical field [0001] The present invention relates to the technical field of power machinery, in particular to a friction material and its products. Background technique [0002] Friction material is a component material that is applied to power machinery and relies on friction to perform braking and transmission functions. It mainly includes brake linings (brake pads) and clutch pads (clutch plates). , The clutch plate is used for transmission, and the friction material is the key component of this kind of brake or transmission. Its main function is to absorb or transmit power through friction. [0003] The transmission or braking function of friction material products must be realized by friction with the counterpart, that is, the friction disc (drum). The surface of the counterpart, namely the friction disc (drum), may be ground into heavier scratches, scratches, grooves and other transitional wear conditions. These conditions are usually referred to as the aggressive...
