Description

technical field [0001] The invention relates to the technical field of friction materials, in particular to a friction material for heavy-duty automobile brake pads. 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. [0003] Due to the large load tonnage and the increase of vehicle speed, heavy-duty vehicles have greater inertia and...
