The invention provides a preparation method of anti-wear carbon/ceramic brake material. First, the short fiber tire net is used to prepare a three-dimensional tire mesh needle-punched preform, and then the carbonized preform is obtained by high temperature heat treatment, vacuum pressure impregnation with resin solution, drying, hot pressing curing, and carbonization treatment; and then vacuum pressure impregnation containing ceramic powder is carried out. The phenolic resin solution or the furfurone resin solution containing ceramic powder is cured and carbonized, and the above steps are repeated to obtain a carbon - carbon composite material with a density of 1.0-1.7g/cm ; The anti-wear carbon/ceramic brake material with a density of 1.9g/cm 3 -3.0g/cm 3 was obtained by the treatment. On the basis of ensuring the mechanical properties and thermophysical properties of the obtained materials, the preparation method of the invention shortens the production cycle of the carbon/ceramic brake material, improves the anti-wear ability and the anti-oxidation ability of the material, and reduces the production cost and improves the brake performance. the goal of. |
