Problems solved by technology

In the process of replacing early asbestos resin friction materials with semi-metallic friction materials, one of the side effects caused by poor handling is the more obvious multiple braking noises.
This frequent low-frequency noise is mainly caused by the existence of a large number of steel fibers in the semi-metallic formula, which greatly reduces the ride comfort of the passengers
Moreover, if the thermal conductivity is too high, it will cause great damage to the brake disc. At the same time, the strength is low and the toughness is poor, which also affects the stability of the friction coefficient of the brake pad.

Description

technical field [0001] The invention relates to the technical field of brake pads, in particular to a high-strength semi-metallic brake pad. Background technique [0002] With the rapid development of science and technology, brake products have higher and higher requirements for friction materials. In addition to safety and comfort under severe working conditions such as high speed, high temperature, and high pressure, energy saving, environmental protection, and cleanliness have been proposed in recent years. Higher requirements. In environmental noise pollution, urban traffic noise has become an important source of pollution. Automobile braking noise endangers the health and comfort of drivers and occupants, and causes unnecessary anxiety to pedestrians on the road and surrounding residents. From a medical point of view, noise of 85-90 decibels is harmful to people, including affecting people's hearing. Today, citizens have a strong reaction to traffic noise. [0003] ...
