This invention discloses a co-curing molding process for large composite material U-shaped stiffened wall panels, including skin panel laying, stringer laying, first tweezer filling, stringer flipping and positioning, intercalation laying, second tweezer filling, stringer cavity laying, curing soft mold laying, soft mold limiting, pressure curing, and demolding. The stringer laying uses a complete composite soft mold as the male mold, achieving dual-purpose use of one mold. During curing, a combination of a complete composite soft mold and split soft molds is used. The complete composite soft mold serves as the main mold, with a thicker thickness and greater vertical edge rigidity. The cooperation between the complete composite soft mold and the soft mold limiting prevents softening and sinking of the vertical edges, thus solving the problem of straightness in the vertical edge length direction. The split soft molds serve as pressure equalizing plate molds. The pressure applied during curing in an autoclave transfers vacuum bag pressure to the split soft molds, and the moving extrusion provides pressure to the vertical edges and radius corners, causing the tweezers and intercalations to return to their theoretical positions under the curing extrusion action, ensuring no damage or problems.
