Ceramic matrix composite bolt based on long-rod-shaped prefabricated body structure
The invention discloses a ceramic-based composite material bolt based on a long-rod-shaped prefabricated body structure, and relates to the technical field of ceramic-based composite material bolt preparation. The method comprises the following steps: designing a prefabricated body structure; preparing a core body structure; weaving a cladding structure; the preparation method comprises the following steps: preparing a ceramic coating, sewing, preparing an interface layer, performing densification treatment, performing thread processing, and finally preparing the ceramic coating by adopting a chemical vapor deposition method, thereby obtaining the ceramic-based composite material bolt based on the long-rod-shaped preform structure. According to the method, the strength of the stud and the strength of the thread teeth are synergistically improved, and the problem that in the prior art, due to the fact that 2D and 3DN bolts are adopted for CMC-SiC mechanical connection, due to non-uniform bearing of the thread teeth, part of the thread teeth are prone to being broken is solved.
本发明公开了一种基于长棒状预制体结构的陶瓷基复合材料螺栓，本发明涉及陶瓷基复合材料螺栓制备技术领域。该方法包括以下步骤：预制体结构设计；制备芯体结构；编制包层结构；缝合，制备界面层，然后进行致密化处理，再进行螺纹加工，最后再采用化学气相沉积法制备陶瓷涂层，制得基于长棒状预制体结构的陶瓷基复合材料螺栓。本发明实现了螺柱强度和螺纹牙强度协同提升，本发明解决了现有技术中CMC‑SiC机械连接所采用2D和3DN螺栓因螺纹牙非均匀承载，而导致部分螺纹牙易发生断齿的问题。
