Preparation method of wear-resistant carbon/ceramic brake material
The invention provides a preparation method of an anti-wear carbon/ceramic brake material. The preparation method comprises the following steps: firstly, preparing a three-dimensional tire net needling prefabricated body by utilizing a short fiber tire net, and then carrying out high-temperature heat treatment, vacuum pressure impregnation in a resin solution, drying, hot-pressing curing and carbonization treatment to obtain a carbonized prefabricated body; then carrying out vacuum pressure impregnation on a phenolic resin solution containing ceramic powder or a furfuryl ketone resin solutioncontaining ceramic powder, carrying out curing and carbonization treatment, and repeating the above steps to prepare a carbon-carbon composite material with the density of 1.01.7 g/cm<3>; and finally,carrying out high-temperature heat treatment and siliconizing treatment to obtain the wear-resistant carbon/ceramic brake material with the density of 1.9 g/cm<3>-3.0g/cm<3>. According to the preparation method disclosed by the invention, on the basis of ensuring the mechanical properties and the thermal physical properties of the obtained material, the production period of the carbon/ceramic brake material is shortened, the wear resistance and the oxidation resistance of the material are improved, and the purposes of reducing the production cost and improving the brake performance are achieved.
本发明提供一种抗磨损碳/陶刹车材料的制备方法。先利用短纤维胎网制备三维胎网针刺预制体,然后经高温热处理、真空压力浸渍树脂溶液、干燥、热压固化、碳化处理制得碳化后的预制体;再进行真空压力浸渍含陶瓷粉体的酚醛树脂溶液或含陶瓷粉体的糠酮树脂溶液,经固化、碳化处理,并重复上述步骤制得密度为1.0‑1.7g/cm3的碳碳复合材料;最后经高温热处理、渗硅处理制得密度为1.9g/cm3‑3.0g/cm3的抗磨损碳/陶刹车材料。本发明制备方法在保证所得材料力学性能、热物理性能的基础上,缩短了碳/陶刹车材料的生产周期,提高了材料的抗磨损能力和防氧化能力,达到了降低生产成本和提高刹车性能的目的。
