Abstract

The invention relates to the technical field of automobile brake material preparation and in particular to a preparation method of a low-wear-type ceramic-based composite bake material. The preparation method comprises the steps: adopting natural organic sponge with an abundant pore structure as a raw material, extracting moso bamboo fiber bundles from moso bamboo, and stacking the sponge and thefiber bundles at intervals; then, carrying out puncturing treatment by using a barbed needle to make the moso bamboo fiber bundles distributed among sponge blocks at a vertical angle to obtain a complex; carrying out carbonization treatment on the complex, then, carrying out vapour fumigation on the complex by using methyltrichlorosilane, and carrying out in-situ deposition under a thermal actionto generate a silicon carbide crystal; and then, soaking the silicon carbide crystal by using tetraethyl orthosilicate to increase the density, and carrying out high-temperature sintering to obtain silicon carbide ceramic brake material. The brake material prepared by using the preparation method is good in wear resistance, high in friction coefficient, not easy to exceed the rated brake power ina brake process and wide in application prospect.

Description

technical field [0001] The invention relates to the technical field of automobile brake material preparation, in particular to a preparation method of a low-wear ceramic matrix composite brake material. Background technique [0002] With the advancement of science and technology and the development of the automobile industry, automobile manufacturing has begun to develop in the direction of light weight and long life. At the same time, higher and higher requirements are placed on the braking system and speed of automobiles. Friction material is the key material of automobile brake friction transmission braking device, and its performance is directly related to the safety and stability of the automobile, as well as the driver's safety and property and other major issues. An ideal friction material should have the advantages of good stability, high friction coefficient, small wear rate, low brake noise, and long service life. [0003] In order to measure the braking performan...
