Friction is a ubiquitous natural phenomenon. Safety work through friction on various vehicles and power machinery around us is a typical use of friction braking and deceleration, which plays a role in the middle of the parts are brake pads made of friction materials, brake shoes, clutches and so on. Brake pads and brake shoes are used for braking, and the clutch is used for transmissão .
Qualquer equipamento mecânico e movimento do veículo deve ter dispositivos de frenagem e transmissão, e pastilhas de freio e almofadas de embreagem são componentes -chave, a função mais importante das pastilhas de freio é garantir a operação normal e segura do equipamento .
Brake pads and clutch pads are composite materials, which are bonded by polymer. Reinforced fiber and friction performance adjustment of the three major material composition, the main performance characteristics is to have a good coefficient of friction and good wear resistance, while having a certain heat resistance and mechanical strength, can meet most vehicles and machinery braking and transmission performance requirements. It is widely used in automobiles, trens de bala, máquinas agrícolas, veículos agrícolas, aeronaves, navios, equipamentos de perfuração e outros tipos de equipamentos mecânicos .
