Ceramic matrix composite part deposition correction tool and method
The invention relates to a ceramic matrix composite part deposition correction tool and method, and aims to solve the problems that in the prior art, when a ceramic matrix composite part prefabricated body with an opening continues to be deposited after demolding, the high-temperature deformation situation occurs, and it is difficult to guarantee that the appearance of a part is accurate when a graphite mold is adopted for deposition correction, the deposition effect is influneced, the graphite mold is relatively high in clamping difficulty, not easy to disassemble and relatively high in cost. The tool comprises at least onecorrection plate made of ceramic matrix composite materials, at least two correction inserting grooves are formed in one side edge of thecorrection plate, and the distance between the correction inserting grooves is matched with the distance between the two side walls, corresponding to an opening, of a to-be-corrected part. The shape of the correction inserting grooves is matched with the profile of the section, close to the opening, of the corresponding side wall of the to-be-corrected part, and the width of the correction inserting grooves is 1-3mm larger than the wall thickness of the to-be-corrected part.
本发明涉及一种陶瓷基复合材料零件沉积校型工装及方法，以解决现有技术中存在的具有开口的陶瓷基复合材料零件预制体在脱模后继续沉积时会出现高温变形情况，而采用石墨模具进行沉积校型难以保证零件外型准确，还会影响沉积效果，且石墨模具装夹难度较大，不易拆卸，成本较高的问题。该工装包括至少一个陶瓷基复合材料的校型板，校型板的一个侧边上设置有至少两个校型插槽，各校型插槽之间的距离与待校型零件对应开口的两侧壁之间的距离相匹配；校型插槽的形状与待校型零件的对应侧壁靠近开口处的截面轮廓相匹配，其宽度比待校型零件壁厚宽1‑3mm。
