Description

technical field [0001] The invention relates to the field of friction materials, in particular to a resin-based friction material for automobiles. Background technique [0002] In recent years, with the rapid development of my country's automobile technology, people pay more and more attention to the safety and comfort of automobiles. Friction material is the key material for brakes and clutches. It is mainly composed of fillers, fibers and binders. Among them, the filler has a great influence on its physical and mechanical properties and wear performance. Traditional friction materials will thermally decompose when the working temperature exceeds 250°C, resulting in a significant decrease in the friction coefficient and a significant increase in the wear rate, seriously affecting people's driving safety. Therefore, the present invention improves the performance of the resin-based friction material in a high-temperature environment from the perspective of the filler and t...
