Ceramic matrix composite annular flanging component and preparation method and tool thereof
The invention relates to a preparation method of a ceramic matrix composite annular flanging component. The preparation method comprises the processes of laying and weaving, mold closing, interface layer deposition and pyrolysis, silicon carbide matrix deposition and repeated machining and silicon carbide matrix deposition. The invention further relates to a ceramic matrix composite material annular flanging component which is a flanging component with non-equal wall thickness and a closed angle, is of an overall structure, is in rotational symmetry and is prepared from a prefabricated body. The invention further relates to a ceramic matrix composite annular flanging component tool which comprises the inner mold, the outer mold and the connecting piece, during mold closing, the inner mold, the outer mold and the prefabricated body are fixed together through the connecting piece, and the prefabricated body is subjected to shape correction through mold closing of the inner mold and the outer mold. The preparation method is used in combination with a tool, the interlayer bonding strength of the component is improved, and the mechanical property of the component is improved. The tool is convenient to transport and operate, the preparation cost is reduced, and knitting at different angles in the knitting process of the 2.5-dimensional prefabricated body is achieved.
本发明涉及一种陶瓷基复合材料环形类翻边构件制备方法，包括铺层与编织、合模、界面层沉积与热解、碳化硅基体沉积、重复机械加工与碳化硅基体沉积的过程。还涉及一种陶瓷基复合材料环形类翻边构件，为非等壁厚且存在闭角的翻边构件，整体结构，旋转对称，由预制体制备而成。还涉及一种陶瓷基复合材料环形类翻边构件工装，包括内模、外模、连接件，合模时，连接件将内模、外模、预制体固定在一起，内模、外模通过合模，对预制体进行校型。本发明制备方法，结合工装使用，提升了构件的层间结合强度，提高了构件的力学性能。本发明工装，运输和操作便捷，降低了制备成本，实现了2.5维预制体编织过程中选用不同角度的编织。
