Problems solved by technology

[0005] For a long time in the past, steel fiber-reinforced semi-metallic brake pads have been the focus of research by researchers. This brake pad was first invented and applied to automobile disc brakes by Bendix Company of the United States. It has stable friction performance, good wear resistance, high braking efficiency and good heat dissipation, but the density of steel fiber is relatively high, and it is easy to rust. After corrosion, it is easy to cause adhesion and affect the shifting separation of the car. And aggravate the wear and tear and damage the pair, and it is easy to produce low-frequency noise of 100-300 Hz, accompanied by severe shaking of the car body and other shortcomings

Description

technical field [0001] The invention belongs to the technical field of automobile brake systems, and in particular relates to an environment-friendly composite material brake pad and a manufacturing process thereof. Background technique [0002] With today's technology, automobiles have become one of the irreplaceable modern tools for human land passenger and cargo transportation, and with the development of my country's economy and society, the number of automobiles is increasing year by year, reaching 33 million in 2005. It can be predicted that the automobile industry will be one of the pillar industries of my country's national economy for a long time to come. [0003] However, while automobiles bring the happiness of modern civilization to human beings, human beings are also bearing the harm it brings. The harm is mainly manifested in three aspects: one is exhaust gas pollution; the other is noise pollution; the third is friction and wear dust pollution. Noise polluti...
