ABSTRACT:
A composite sandwich structure is produced by providing a core structure, applying cover layers on opposite sides of the core structure, and forming an edge seal. The core structure has a folded cell structure with fold valleys forming continuous open channels with open ends and/or open channel sides at edges of the core structure. The channels extend along and are bounded between the fold valleys and the cover layers. The edge seal is formed to have a limited spatial volume in an edge region at an edge of the core structure, to close and seal open ends and/or open channel sides of the channels of the core, without an uncontrolled penetration of the seal material from the edge region to a greater depth into the open channels.
