Abstract

The invention discloses a mold for manufacturing ribbed composite material reinforced wallboards, which belongs to the technical field of reinforced wallboard manufacturing. A mold for manufacturing ribbed composite material reinforced wallboards comprises templates, positioning brackets and panel preforming Body, positioning support rods and hat-shaped stiffener outer soft molds, stiffener preforms, and stiffener inner soft molds that are set sequentially from the inside to the outside; Forming and assembling are easy to assemble and disassemble, and the mold combined with flexible material and metal material can protect the rib preform and panel preform very well, improving the production efficiency and forming quality of the reinforced wall panel; The invention also discloses a method for manufacturing ribbed composite material reinforced wall panels, using a complete set of templates, a better molding process and a detailed treatment method, the finished product has a regular surface of the ribs, uniform thickness, and stable product quality Reliable advantages, easy operation and easy positioning.

Description

technical field [0001] The invention relates to the technical field of manufacturing reinforced wall panels, in particular to a mold and method for manufacturing a hat-shaped composite material reinforced wall panel. Background technique [0002] The hat-shaped composite material reinforced wall plate structure is a composite structure with high cost-effectiveness ratio, and its typical advantages are fewer connectors, good rigidity, and long fatigue life. The fuselages of the latest models of B787 and A350 wide-body airliners have adopted cap-shaped composite material reinforcement structures. The hat-shaped composite material reinforced structure is composed of hat-shaped ribs and panels. Compared with T-shaped, J-shaped, and I-shaped reinforced wall panels, the structure is simpler, and co-curing (curing of panels and ribs at the same time) and co-glue are generally used. Connecting (curing the panel first, then bonding and curing with the reinforcing rib in the prepreg ...
