MOLDING PROCESS FOR CORE-CONTAINING COMPOSITES AND COMPOSITES FORMED THEREBY

摘要

A process for producing composite structures (10) having a core (14) between resin- impregnated composite layers (18), and composite structures formed by such a process. The process uses non-impregnated fabric layers (18) and a core layer (14) placed on a mold (34) such that the core layer is between at least two fabric layers, a first of which is disposed between the mold surface and a first surface of the core layer, and a second of which is disposed at a second surface of the core layer. The second fabric layer is then infused with a resin, which flows through holes in the core layer into the first fabric layer, such that the first and second fabric layers are uniformly impregnated with the resin and the core layer is not. The resin is then cured to cause the impregnated first and second fabric layers to bond to the core layer.
