According to the ceramic based friction materials with the high stability, an excellent thermal conductivity property is achieved, the stability of the friction materials is guaranteed, the heat fading resistance of the friction materials is improved, good and stable braking force output is provided, and the long service life and the comfort are achieved.

Description

technical field [0001] The invention relates to a high stability ceramic base friction material. Background technique [0002] In today's world, with the advancement of science and technology, more new technologies are applied to the field of automobile manufacturing, which also makes the automobile develop towards high speed and high load; at the same time, people also put forward particularly high requirements for comfort. The improvement of braking technology requirements is not only reflected in ensuring safety. Friction material products should not only meet the requirements of braking, but also meet the requirements of low noise, long life, low dust, and non-aggressive duality. [0003] With the enhancement of environmental protection awareness in various countries, the intensity of environmental protection is getting stronger and stronger, and their respective regulations and requirements have been introduced one after another to limit the composition of friction mat...

AI Technical Summary

Problems solved by technology

However, the performance of the existing ceramic-based brake pads is not stable enough. Many brake pads tend to decline in friction performance and tend to lock or drag at high temperatures.

At the same time, due to the unreasonable combination of components, the metal mosaic phenomenon occurs

Sometimes there are even serious quality problems such as friction material expansion and friction surface cracks; at the same time, due to restrictions on the use of copper, traditional copper-containing friction materials cannot meet new environmental protection requirements
