Abstract

The invention proposes a stable and wear-resistant composite ceramic-based friction material, which comprises the following raw materials in parts by weight: 5-15 parts of mineral fiber, 15-30 parts of ceramic fiber, 3-12 parts of aramid fiber, cashew nut 10-20 parts of oil-modified phenolic resin, 5-8 parts of metal sulfide, 10-20 parts of anti-wear lubricant, 10-25 parts of friction performance regulator, 8-20 parts of filler; the mineral fiber is carbon / carbonized Silicon composite fiber material. The raw materials of the friction material proposed by the present invention are reasonably matched, can effectively stabilize the friction system, improve the fading, increase the friction life of the brake pad and the pair, and improve the comfort of the brake. At the same time, it has good heat dissipation performance and improves the wear life of the disc. , reduces the formation of cracks on the surface of the brake disc, and has no noise, less ash falling, high temperature resistance, and can be widely used in many 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...
