Abstract

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.

Description

technical field [0001] The invention belongs to a C / SiC composite material prefabricated body molding tool and method, in particular to a shaping tool and a C / SiC composite material structural member molding method using the shaping tool. Background technique [0002] Cabin-like C / SiC composite structural parts generally have large dimensions, a large number of grids, and complex curved surfaces. The existing forming process is generally to split a large structural part into multiple small structural parts, first form a single small part and then rivet and weld the assembly. When assembled by conventional rivet welding process, there are often problems of narrow local space, difficult operation and low assembly accuracy. And in the rivet welding process, the pores between the grids are relatively large. Contents of the invention [0003] The main purpose of the present invention is to solve the existing technical problems of narrow local space, difficult operation and lo...
