Concave-like ceramic matrix composite material connecting part forming mold and using method of concave-like ceramic matrix composite material connecting part forming mold
The invention relates to a concave-like ceramic matrix composite material connecting part forming mold and a technological method. The technical problems that an existing C/SiC composite material connecting part is formed by independently forming a plurality of small components and then assembling, riveting and welding, riveting cannot be achieved due to the limitation of the part height in the assembling process, and the penetration risk exists in the cut part in the shaping process of the single small component are solved. The invention provides a ceramic matrix composite material connecting part forming die and a process method. The method comprises the following steps: splitting a connecting part into a plurality of small components, carrying out carbon pre-deposition on the plurality of small components, then carrying out assembly sewing, continuing carbon deposition on a sewn prefabricated body, and when the skeleton prefabricated body is shaped, carrying out layering on carbon fiber cloth by adopting a crisscross method. According to the invention, the problem that the middle part cannot be deposited on the carbon interface layer due to the thicker wall thickness of the prefabricated body can be effectively solved, so that the overall strength of the connecting part is improved, and meanwhile, the problem of penetration caused by local continuous cutting of the carbon cloth is also solved.
本发明涉及一种类凹型陶瓷基复合材料连接部件成型模具及工艺方法。解决了现有C/SiC复合材料连接部件由多个小型构件单独成型后再组装铆焊成型，在组装时受零件高度限制，导致无法铆接，且在单个小型构件在定型时，裁剪部位存在穿透风险的技术问题，提供一种陶瓷基复合材料连接部件成型模具及工艺方法。通过将连接部件拆分成多个小组件，并对多个小组件进行预沉碳后，再进行组装缝制，对缝制后的预制体继续进行沉碳，在骨架预制体定型时，采用十字交叉的方法对碳纤维布进行铺层。通过本发明可以有效解决预制体因壁厚较厚造成中间部位无法沉积到碳界面层的问题，从而提高了连接部件的整体强度，同时还解决了因局部连续裁剪碳布造成穿透的问题。
