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...
