Friction materials and machinery
1. Friction material: It is a kind of polymer ternary composite material, which is a physical and chemical composite. It is composed of three types of polymer binder (resin and rubber), reinforcing fiber and friction performance modifier, and other coordination Agent composition, products made through a series of production processes.
It is characterized by a good coefficient of friction and wear resistance, as well as a certain degree of heat resistance and mechanical strength, which can meet the performance requirements of vehicles or machinery for transmission and braking. It is widely used in the brake and clutch friction linings of vehicles, trains, airplanes, etc., especially the brake linings and clutch facings, which are very important security parts, and their performance directly affects the stability of the machine and the safety of passengers. Therefore, there are strict requirements in the manufacturing, quality control, and inspection processes.
Its main function is to absorb or transmit power through friction. For example, clutch plates transmit power and brake plates absorb kinetic energy. They enable mechanical equipment and various motor vehicles to work safely and reliably. Therefore, friction materials are widely used. What a crucial material. In most cases, friction materials are rubbed against various metals. It is generally recognized that under dry friction conditions, materials with a friction coefficient of more than 0.2 are called friction materials.
