High-bending-strength carbon ceramic brake disc and preparation method thereof
The invention relates to the field of carbon-ceramic composite materials, and particularly discloses a high-bending-strength carbon-ceramic brake disc and a preparation method thereof.The preparation method comprises the following steps that S1, carbon cloth is sheared and then directly placed in a graphite mold in a laminated mode, and the carbon cloth is directly subjected to vapor deposition along with the graphite mold after being pressed in the graphite mold; s2, high-temperature treatment: taking out the carbon-carbon green body after vapor deposition from the graphite mold, and performing high-temperature treatment to obtain the carbon-carbon green body; s3, siliconizing treatment: performing siliconizing ceramic treatment on the carbon-carbon green body treated in the step S2; s4, mechanical polishing is conducted, and the carbon-ceramic brake disc is prepared; the invention further discloses the high-bending-strength carbon-ceramic brake disc prepared through the preparation method. The high-bending-strength carbon-ceramic brake disc has the advantage that the high-bending-strength carbon-ceramic brake disc is better in bending strength.
本申请涉及碳陶复合材料领域，具体公开了一种高抗弯强度碳陶刹车盘及其制备方法，制备方法包括以下步骤：S1、将碳布剪切后直接叠层放置在石墨模具内，碳布在石墨模具内被压紧后随石墨模具直接进行气相沉积；S2、高温处理，将气相沉积后的碳碳坯体从石墨模具取出后进行高温处理，制得碳碳坯体；S3、渗硅处理：对步骤S2处理后的碳碳坯体进行渗硅陶瓷化处理；S4、机械打磨，制得碳陶刹车盘；本申请还公开了采用上述制备方法制得的高抗弯强度碳陶刹车盘，本申请具有制备抗弯强度更好的碳陶刹车盘的特点。
