Preparation method of carbon-ceramic composite material
The invention relates to a preparation method of a carbon-ceramic composite material. The preparation method comprises the following steps: step 1, preparing a C/C preform; step 2, carrying out high-temperature pretreatment on the C/C prefabricated body; 3, preparing a carbon ceramic precursor A by adopting a chemical vapor infiltration method; step 4, carrying out graphitization treatment on the prepared carbon ceramic precursor A; 5, preparing a carbon-ceramic precursor B by adopting a dipping and carbonization densification treatment process; step 6, carrying out melt siliconizing treatment on the obtained carbon ceramic precursor B; and 7, performing high-temperature treatment on the obtained carbon-ceramic composite material to remove residual silicon. The carbon-ceramic brake disc made of the carbon-ceramic composite material produced by the preparation method is uniform in organization structure and stable in brake performance, and the friction and wear performance of the carbon-ceramic brake disc is further improved.
本发明涉及一种碳陶复合材料的制备方法，所述制备方法包括以下步骤：步骤1、C/C预制体的制备；步骤2、对C/C预制体进行高温预处理；步骤3、采用化学气相渗透法制备碳陶前驱体A；步骤4、对制备的碳陶前驱体A进行石墨化处理；步骤5、采用浸渍、炭化增密处理工艺，制备碳陶前驱体B；步骤6、对获得的碳陶前驱体B进行融熔渗硅处理；步骤7、对获得的碳陶复合材料进行高温处理以去除残余硅。所述制备方法生产的碳陶复合材料制造的碳陶刹车盘，组织结构均匀、刹车性能稳定，进一步提高了碳陶刹车盘的摩擦磨损性能。
