Preparation method of sandwich structure carbon/ceramic brake disc for automobile
The invention provides a preparation method of a sandwich structure carbon/ceramic brake disc for an automobile, which comprises the following steps: firstly preparing a three-dimensional needling preform, placing the prepared preform in a chemical vapor deposition furnace for deposition treatment, machining the treated preform into a matrix according to the size requirement of a finished product by adopting a machining method, and carrying out heat treatment on the matrix to obtain the sandwich structure carbon/ceramic brake disc for the automobile. The preparation method comprises the following steps: preparing a wear-resistant coating, brushing the wear-resistant coating on a single side of a matrix, drying, repeatedly brushing until the wear-resistant coating on the single side reaches the required thickness, finally, carrying out heat treatment on the matrix attached with the wear-resistant coating in a vacuum environment, completely converting carbon in the matrix into resin carbon, and raising the temperature to generate the high-density carbon-ceramic composite material. According to the wear-resistant coating, the wear resistance of the carbon/ceramic brake material is improved, the service life of the carbon/ceramic brake material is prolonged, the shaking problem in the braking process can be effectively reduced, the components of the wear-resistant coating can be proportionally adjusted according to the brake performance requirements of different vehicle types, and the applicability is wide.
本发明提供了一种汽车用夹芯结构碳/陶制动盘的制备方法，包括以下步骤：先制备三维针刺预制体，将制备好的预制体，置于化学气相沉积炉中进行沉积处理，处理后的预制体采用机械加工的方法，按照成品尺寸要求加工出基体，并将耐磨涂层在基体上进行单面涂刷，烘干后反复涂刷至单边的耐磨涂层达到要求厚度，最后将附着有耐磨涂层的基体在真空环境下进行热处理，将基体中的碳全部转换为树脂碳，然后升高温度，生成高密度碳陶复合材料。本发明中的耐磨涂层提升碳/陶刹车材料的耐磨性、延长其使用寿命，可有效减少刹车过程中的抖动问题，耐磨涂层成分可以根据不同车型刹车性能要求进行配比调节，应用性广。
