Problems solved by technology

[0003] Carbon / ceramic composite materials mainly contain three components: carbon, silicon and silicon carbide, and the carbon in it is mainly composed of carbon fiber and matrix carbon. These two carbon components can remain stable at room temperature and will not occur. Change, but it is easy to be oxidized at a temperature above 500°C; when exposed to high temperature for a long time, the brake disc made of carbon / ceramic composite material may have grooves or other damage on the surface due to oxidation, which will affect the performance of the brake disc. Braking performance, leading to increased brake pad wear
[0004] At present, the price of carbon / ceramic brake discs on the market is relatively high. If it is directly scrapped due to damage, it will cause waste. Therefore, in order to avoid waste, it is very necessary to repair carbon / ceramic brake discs.

Embodiment 1

[0022] A method for repairing an automobile carbon-ceramic brake disc. The method includes five steps. The first step is to clean the brake disc to be repaired. The second step is to impregnate the carbon fiber cloth with resin. The third step is to carbonize the resin. finishing.

[0023] After the surface of the brake disc to be repaired is polished, it is cleaned and dried to prepare carbon fiber cloth, which is soaked in resin and adhered to the surface of the brake disc to carbonize the resin. / Tao Brake Disc.

[0024] The outer side of the brake disc body is a repair layer.

Embodiment 2

[0026] A method for repairing an automobile carbon-ceramic brake disc described in Example 1, the first step of cleaning the brake disc to be repaired is to clean the sundries on the brake disc to be repaired with pure water, and then clean the surface Polish and smooth, then clean and dry; the second step of impregnating carbon fiber cloth with resin is to mix liquid thermosetting resin and curing agent, and obtain a uniformly dispersed resin mixture after stirring, fully soak the carbon cloth woven with carbon fiber in the resin; then adhere the impregnated carbon cloth to the surface of the cleaned brake disc; the third step of resin carbonization is to put the brake disc adhered to the carbon cloth into a vacuum graphitization furnace, and after the furnace is evacuated Fill the protective gas, maintain normal pressure in the furnace, and carry out graphitization treatment on the carbon cloth adhered to the resin at high temperature; in the fourth step of molten siliconizin...

Embodiment 3

[0028] A kind of repair method of automobile carbon ceramic brake disc described in embodiment 1 or 2, the thermosetting resin of described second step is phenolic resin or epoxy resin; The curing agent of described second step is p-toluene Sulphonic acid or phthalic anhydride; the carbon cloth in the second step is made of carbon fiber net tire transverse layup, and then longitudinal needle punching;

Description

technical field [0001] The invention relates to a method for repairing an automobile carbon ceramic brake disc. Background technique [0002] At present, gray cast iron is commonly used as the material of brake discs. This material is heavy, has a low melting point, and is easy to deform. Disc, this kind of brake disc has the advantages of low density, high temperature resistance, high strength, good friction performance and long service life. [0003] Carbon / ceramic composite materials mainly contain three components: carbon, silicon and silicon carbide, and the carbon in it is mainly composed of carbon fiber and matrix carbon. These two carbon components can remain stable at room temperature and will not occur. Change, but it is easy to be oxidized at a temperature above 500°C; when exposed to high temperature for a long time, the brake disc made of carbon / ceramic composite material may have grooves or other damage on the surface due to oxidation, which will affect the pe...
