Layered structure carbon ceramic brake disc and preparation method thereof
The invention relates to a layered structure carbon ceramic brake disc and a preparation method thereof, and relates to the technical field of carbon ceramic brake discs, and the preparation method comprises the following steps: preparing a carbon/carbon preform with the thickness of 5-10 mm by adopting a needling process; depositing a carbon layer on the carbon/carbon preform, and performing rough machining to obtain a carbon/carbon composite material; and a plurality of carbon/carbon composite materials are bonded, finish machining is conducted, then siliconizing treatment is conducted, and the carbon-ceramic brake disc is obtained. Carbon/carbon composite materials of multiple specifications and sizes are prepared in advance, the carbon/carbon composite materials are semi-finished products used for preparing the carbon-ceramic brake disc, the multiple carbon/carbon composite materials of the same size are bonded according to the needs of customers, finish machining and siliconizing treatment are sequentially conducted after bonding, and the carbon-ceramic brake disc of the layered structure is prepared. The production cycle, especially the siliconizing cycle, can be greatly shortened, the supply speed is increased, the production flexibility is high, and the method is suitable for multi-variety and small-batch production.
本申请涉及一种层状结构碳陶制动盘及其制备方法，涉及碳陶制动盘技术领域，制备方法包括：采用针刺工艺制备厚度为5‑10mm的碳/碳预制体；在碳/碳预制体上沉积碳层，粗加工后制得碳/碳复合材料；将若干碳/碳复合材料粘合，精加工后再经渗硅处理，制得碳陶制动盘。本申请预先制备若干规格尺寸的碳/碳复合材料，该碳/碳复合材料是用于制备碳陶制动盘的半成品，根据客户的需要将相同尺寸的若干碳/碳复合材料进行粘合，粘合后依次进行精加工、渗硅处理，制得层状结构碳陶制动盘，通过制备半成品，可以大幅缩短生产周期，尤其是渗硅周期，提高供货速度，生产柔性高，适合多品种、小批量生产。
