The present invention is a method for making a composite structure that includes three resin impregnated structural cloth layers including a bottom sheet, a top sheet and a core sheet. The core sheet is a continuously curved shape with flat valleys that are bonded to the bottom sheet and flat peaks that are bonded to the top sheet. In the invention process, a dry core sheet is sandwiched between two wax core molds that form the core sheet. The core molds and the core sheet are sandwiched between dry top and bottom sheets by rigid molds as the flat peaks and valleys of the core sheet make contact with the top and bottom sheets through openings in the core molds. Liquid resin is transferred into the dry sheets and then cured. The lay up is disassembled and the wax core molds are melted and drained from the finished, rigid structure.
