Mould pressing manufacturing method of carbon-carbon crucible support
The invention relates to the technical field of carbon-carbon composite materials, in particular to a mould pressing manufacturing method of a carbon-carbon crucible support. Comprising the following steps: step 1, preparing a carbon fiber preform; step 2, carbon fiber preform impregnation; step 3, forming a carbon fiber preform; 4, carrying out primary carbonization; step 5, densification is carried out; step 6, carrying out secondary carbonization; step 7, obtaining the ash content of the product; step 8, machining; and 9, chemical vapor deposition is conducted, specifically, the machined product is subjected to chemical vapor deposition surface coating treatment, the temperature ranges from 1000 DEG C to 1100 DEG C, carbon source gas and diluent gas are introduced, and the deposition time ranges from 20 h to 60 h. The carbon-carbon crucible support is prepared in a mold pressing mode, the production time can be shortened, compared with the mode that the carbon-carbon crucible support is prepared through prefabricated body manufacturing and chemical vapor deposition, mold pressing can save the production time by 30%-60%, the product size stability is good, the surface is smooth and clean, and the machining efficiency is improved.
本发明涉及碳碳复合材料技术领域，特别涉及一种碳碳埚托的模压制作方法。包括以下步骤：步骤1、制备碳纤维预制体；步骤2、碳纤维预制体浸渍；步骤3、碳纤维预制体成型；步骤4、一次碳化；步骤5、增密；步骤6、二次碳化；步骤7、产品灰分；步骤8、机加；步骤9、化学气相沉积：对机加后的产品进行化学气相沉积表面涂层处理，温度为1000～1100℃，通入碳源气体和稀释气体，沉积时间为20～60h。本发明通过模压的方式制备碳碳埚托可以减少生产时间，相较于制作预制体加化学气相沉积制备碳碳埚托的方式，模压能够节约30～60％的生产时间，且产品尺寸稳定性好，表面光洁，提高机加工的效率。
