Preparation method for automatic forming of carbon-carbon composite PECVD bearing frame
The invention relates to the technical field of PECVD (Plasma Enhanced Chemical Vapor Deposition) bearing frames, and provides a preparation method for automatically forming a carbon-carbon composite material PECVD bearing frame. The preparation method comprises the following steps: laying prepreg carbon cloth by adopting an automatic cloth laying machine, placing the obtained laid prepreg in a silicone rubber bag for vacuumizing, and then curing in a drying oven to obtain a preform; and carrying out carbonization, chemical vapor deposition densification and machining on the prefabricated body to obtain the carbon-carbon composite PECVD bearing frame. According to the method, common prepreg carbon cloth is adopted as a raw material, then laying is conducted through automatic equipment, the production efficiency of the product can be improved, the stability of the product quality can be guaranteed, in addition, the laid prepreg is placed in a vacuum bag, curing is conducted through a drying oven, energy consumption can be effectively reduced, and the cost can be effectively reduced. In conclusion, the preparation method provided by the invention is high in production efficiency, stable in product quality and low in energy consumption and production cost.
本发明涉及PECVD承载框技术领域，提供了一种碳碳复合材料PECVD承载框自动化成型的制备方法。本发明采用自动铺布机将预浸料碳布进行铺层，将所得铺层预浸料置于硅橡胶袋中进行抽真空，然后在烘箱中进行固化，得到预制体；将所述预制体进行碳化、化学气相沉积增密和机加工，得到碳碳复合材料PECVD承载框。本发明采用常用的预浸料碳布为原料，然后通过自动化设备进行铺层，既能提高产品的生产效率，又能保证产品质量的稳定性，另外，本发明将铺层预浸料置于真空袋中，采用烘箱进行固化，能有效降低能耗，减低成本。综上所述，本发明提供的制备方法生产效率高，产品质量稳定，且能耗和生产成本低。
