Abstract:
1. A core structure for producing a composite sandwich structure having a local reinforcement zone therein by later applying respective first and second cover layers respectively on opposite first and second sides of said core structure, wherein said core structure includes a core having a folded configuration with fold valleys forming open channels extending therealong, and said local reinforcement zone permanently connected on said core, wherein said local reinforcement zone comprises, respectively as first and second reinforcements, a first molded body arranged form-fittingly and locally spatially limited on only a partial surface area on said core on said first side of said core structure, and a second molded body arranged form-fittingly and locally spatially limited on only a partial surface area on said core on said second side of said core structure, wherein said first and second molded bodies are respectively permanently connected to said core on said opposite first and second sides in a force-transmitting manner by respective permanent force-transmitting connections selected from a glued connection, a cast connection, a foamed connection, a potted connection, a welded connection, a brazed connection or a soldered connection; wherein said first and second molded bodies respectively have opposite planar first and second molded body surfaces that define a thickness of said core structure therebetween and that are positioned and adapted to receive said first and second cover layers respectively applied onto said opposite planar first and second molded body surfaces, and wherein said core structure does not have said first cover layer on said first side of said core structure and does not have said second cover layer on said second side of said core structure.
