Abstract: A composite wing panel is disclosed. In one embodiment, a wing panel for an aircraft includes an external skin having a substantially smooth laminar surface, the external skin including multiple layers of a cured material; a sealed core material located within the external skin, the core material having first and second side opposing sides and having been substantially evacuated of air; and a support element disposed within the external skin, the external skin and support element being co-bonded or co-cured together.

Abstract: A system for manufacturing a molded composite structure is disclosed.

Abstract: A method for molding composite structures whereby a material stack including a core having first and second opposing sides is prepared. The preparing of the material stack includes applying a fibrous support layer on at least one of the first side and the second side of the core section, applying an adhesive layer on the support layer, and applying a thermoplastic barrier layer on the adhesive layer. The method also includes preparing a resin and a mold; placing the material stack in the mold; sealing the core; infusing the mold and material stack with resin; curing the structure; and removing the structure from the mold. In one embodiment, the method creates a composite aircraft wing panel.

Abstract: A molded composite structure and a method of manufacturing a molded composite structure are disclosed. In one embodiment, an aircraft wing panel and a method for manufacturing an aircraft wing panel are disclosed. In another embodiment, the method of manufacturing a molded composite structure uses a resin transfer molding process.
