Abstract

The invention provides a composite ceramic-based friction material with high stability and abrasion resistance. The composite ceramic-based friction material comprises, by weight, 5-15 parts of mineral fibers, 15-30 parts of ceramic fibers, 3-12 parts of aramid fibers, 10-20 parts of cashew nut oil modified phenolic resin, 5-8 parts of metal sulfide, 10-20 parts of a wearing-resistant lubricant, 10-25 parts of a friction performance modifier and 8-20 parts of filler. The mineral fibers refer to a carbon / silicon carbide composite fiber material. According to the friction material provided by the invention, the raw materials are matched reasonably, a friction system can be effectively stabilized, the problem of recession is solved, the friction service life of brake pads and couplings is prolonged, and the comfort level in braking is increased; meanwhile, the heat dissipation performance is good, the abrasion service life of discs is prolonged, and the number of surface cracks of the brake discs is decreased; and moreover, noise can be avoided, the amount of dust falling off is small, high-temperature resistance can be achieved, and the composite ceramic-based friction material can be widely applied to various fields.

Description

technical field [0001] The invention relates to the technical field of friction materials, in particular to a stable and wear-resistant composite ceramic-based friction material. Background technique [0002] Automobile brake pads are the key components of Class A of the automobile braking system, and their performance is directly related to the safety and reliability of automobile operation. As a friction material for brake pads, while satisfying the braking performance in normal use, its service life, environmental protection and comfort are also a problem that people are very concerned about. Friction materials are composed of several or even more than a dozen different components to achieve the expected stable friction coefficient and high wear resistance. These components mainly include matrix, reinforcing materials, and friction modifiers. Semi-metallic, metallic, organic and carbon-based friction materials have been extensively studied, however, their application sco...
