Description

technical field [0001] The invention relates to the technical field of brake pads, in particular to a low-noise and high-temperature-resistant brake pad. Background technique [0002] With the development of automobile technology application in the direction of environmental protection, high speed and heavy load, higher requirements are put forward for the stability and reliability of the automobile braking system, and the comprehensive performance of the friction material of the brake pad will directly affect the performance of the automobile during driving. Safe and comfortable. The essence of automobile braking is to convert most of the kinetic energy of the automobile into heat energy through the friction between the brake pad and the brake disc (or drum), and most of the heat energy is absorbed by the brake to cause the temperature to rise. At present, the automobile brake pads that appear on the market still have the defects of poor high temperature resistance, unsati...
