Shaping tool and C/SiC composite structural part forming method adopting shaping tool
The invention belongs to C/SiC composite preform forming tools and methods, and provides a shaping tool and a C/SiC composite structural part forming method adopting the shaping tool in order to solvethe problems that the forming process that after single parts are formed, then rivet welding and assembling are carried out is adopted by an existing C/SiC composite structural part, during assembling, the local space is narrow, operation is difficult, and the assembling precision is low. The shaping tool comprises an arch-shaped shaping top plate, and the shaping top plate is mounted on a shaping bottom plate. The back sides of the shaping top plate and the shaping bottom plate are bent inwards to form shaping supporting edges, multiple limiting grooves are formed in the shaping top plate and the shaping bottom plate, and limiting slabs are clamped in the limiting grooves. According to the forming method, shaping supporting is carried out through a box-shaped assembly, the thickness of carbon fiber cloth of the box-shaped assembly is adjusted through the limiting grooves and the limiting slabs, and the smoothness and thickness consistency of the carbon cloth is guaranteed. Laying whole cloth is subjected to flanging treatment, a flanged and cut opening is reinforced, and therefore the overall strength of a composite is guaranteed. A C/SiC composite structural part is firstly shaped and then deposited.
本发明属于C/SiC复合材料预制体成型工装及方法，为解决现有C/SiC复合材料结构件采用单个零件成型后再铆焊组装的成型工艺，在组装时存在局部空间狭窄，操作困难，装配精度低的问题，提供定型工装及使用定型工装的C/SiC复合材料结构件成型方法。定型工装包括拱形的定型顶板，定型顶板安装于定型底板上，定型顶板和定型底板的背侧向内弯折形成定型支撑沿，定型顶板和定型底板上均开设有多个限位槽，限位平板卡接于限位槽内。成型方法是利用盒型组件进行定型支撑，限位槽和限位平板调整盒型组件的碳纤维布厚度保证了碳布的平整和厚度一致；翻边处理垫铺整布，对翻边裁剪口部位进行补强，保证了复合材料的整体强度。先对C/SiC复合材料结构件定型，再进行沉积。
