Problems solved by technology

Brake pads made of steel fibers as reinforcing fibers are prone to rust and adhere to the counterpart in a humid or corrosive environment, damaging the counterpart and thus affecting the braking effect, and have the defect of high wear rate; brake pads made of asbestos as reinforcing fibers Due to the high temperature generated by the brakes, the crystal water contained in the asbestos is instantly lost, resulting in asbestos ablation, resulting in thermal degradation of the braking performance of the brake pads, and at the same time, the wear of the brake pads itself is intensified, and asbestos will produce harmful substances at high temperatures. The country has promulgated regulations in October 2003 to prohibit the use of asbestos in the production of brake pads
Since the braking effect of the brake pads has a great impact on driving safety and production safety, it is required that the brake pads should have the characteristics of moderate friction coefficient, low wear rate, good thermal decay resistance, and long life. To quantify the trend, the friction material is also required to be compact and light in weight. The brake pads made of steel fiber friction materials currently used have the disadvantages of high wear rate, short life and high quality. The brake pads made of inorganic asbestos friction materials currently used, It has the disadvantages of poor heat decay resistance, short life, and harmful substances
