ABSTRACT:
Producing a composite structure involves providing a core structure having a folded configuration with fold valleys forming open channels extending along the valleys, and then forming a local reinforcement zone in the core structure itself, before applying any cover layer onto the core structure. The method may further involve applying two cover layers on two opposite sides of the core structure to form a composite sandwich structure, after the local reinforcement zone has been formed in the core structure. A core structure preferably has a local reinforcement zone formed by two molded bodies, e.g. of cured synthetic resin or foam, arranged form-fittingly on the opposite sides of the core.
