Abstract

The invention discloses a composite material curved surface stiffened wall plate integral forming mold and a manufacturing method and belongs to the technical field of structural composite material manufacturing. The mold comprises an upper mold body, a lower mold body and at least one core block mold body. The upper mold body comprises a composite material curved surface stiffened wall plate profile feature structure and a feature structure in limiting fit with the lower mold body. The fitting face of the core block mold body is an inclined plane. The core block mold body and the lower mold body are in concave and convex fit. The mold is utilized for integrally manufacturing a composite material curved surface stiffened wall plate, the follow-up machining working procedure of the composite material curved surface stiffened wall plate can be reduced, and the manufacturing efficiency and the manufacturing quality of the composite material curved surface stiffened wall plate are improved.

Description

technical field [0001] The invention belongs to the technical field of structural composite material manufacturing technology, and in particular relates to an integrated forming mold and a manufacturing method of a composite material curved surface reinforced wall plate. Background technique [0002] Reinforced panel structure is a commonly used structural form of various aerospace structures. Its structural lightweight level, process manufacturability, manufacturing efficiency and cost are the keys to compacting and expanding its application range. At present, the reinforced wall panel structure made of metal material is heavy, which reduces the lightweight level of the overall system; the reinforced wall panel structure made of composite material has low manufacturing efficiency and high cost. Therefore, how to ensure that the reinforced wall panel structure has a high level of lightweight and manufacturable technology is a problem that the relevant industry needs to solve...
