Preparation method of pure mesh tire structure carbon/ceramic composite material brake disc blank
The invention belongs to the technical field of carbon/ceramic composite materials, and particularly relates to a preparation method of a pure mesh tire structure carbon/ceramic composite material brake disc green body, which comprises the following steps: preparing a pure mesh tire three-dimensional integral needled carbon felt; carrying out pyrolytic carbon deposition by adopting a chemical vapor deposition method; putting the deposited three-dimensional integral needled blank with the pure net tire structure into a high-temperature furnace for heat treatment; putting the three-dimensional integral needled green body with the pure mesh tire structure after heat treatment into a crucible containing a certain amount of self-made permeating agent, and putting the three-dimensional integral needled green body and the self-made permeating agent into an infiltration furnace together for modification treatment; and then high-temperature heat treatment is carried out to obtain a carbon/ceramic composite material green body subjected to ceramic post-heat treatment, so that the problem of poor performance consistency and stability of the carbon/ceramic composite material brake disc caused by large difference of reinforcement materials is solved.
本发明属于碳/陶复合材料技术领域，尤其涉及一种纯网胎结构碳/陶复合材料刹车盘坯体的制备方法，包括：制备纯网胎三维整体针刺碳毡；采用化学气相沉积方法，进行热解碳沉积；将沉积后的纯网胎结构三维整体针刺坯体放入高温炉中热处理；将热处理后的纯网胎结构三维整体针刺坯体放入含一定量自制渗剂的坩埚中，并一同放入熔渗炉中进行改性处理；再进行高温热处理，得到经过陶瓷化后热处理的碳/陶复合材料坯体，解决因增强体材料差异较大，而引起碳/陶复合材料刹车盘性能一致性和稳定性差的问题。
