Continuous ceramization preparation method of C/C-SiC brake disc
The invention relates to a continuous ceramization preparation method of a C/C-SiC brake disc, and belongs to the technical field of ceramic materials. The method comprises the following steps: densifying a carbon fiber preform, machining into a carbon/carbon composite material part, putting into a container, arranging a supporting block between the part and the container to form a gap, filling silicon powder into the gap and ensuring that the height of the silicon powder does not exceed the lower bottom surface of the part to form an assembly; and more than one assembly is subjected to silicon reaction infiltration ceramization treatment through continuous high-temperature reaction, and the C/C-SiC brake disc is prepared. The carbon/carbon composite material part is siphoned through a supporting block made of a porous material, and rapid reaction infiltration is realized under a continuous high-temperature condition, so that a product with uniform ceramic distribution and controllable ceramic content is prepared; the structural strength of the prepared brake disc is superior to that of the same type of products produced in the prior art, the uniformity of the ceramic matrix is superior to that of resin doping impregnation, uniform permeation of thick products is facilitated, the manufacturing period is short, the raw material cost is low, and continuous batch production can be achieved.
本发明涉及一种C/C‑SiC制动盘连续陶瓷化制备方法，属于陶瓷材料技术领域。通过将炭纤维预制体增密，再机械加工成炭/炭复合材料部件，然后置于容器中，在部件和容器之间设支撑块形成间隙，将硅粉填充在间隙中并高度不超过部件下底面，形成组合件；将一个以上的组合件用连续高温反应进行硅反应熔渗陶瓷化处理，制得C/C‑SiC制动盘。利用炭/炭复合材料部件通过多孔材料的支撑块虹吸，在连续高温条件下实现快速反应熔渗，进而制得陶瓷分布均一且陶瓷含量可控的产品；制备的制动盘结构强度优于现有技术生产的同类型产品，陶瓷基体均一性优于树脂掺杂浸渍，利于较厚产品的均匀渗透，制作周期短，原料成本低，可连续批量化生产。
