Abstract: A sandwich structure is provided that includes a corrugated layer with at least one core layer (structure) made of a periodic array of adjacent truncated upward facing peaks and truncated downward facing valleys. Each truncated peak has a bonding land of an area A1. Each truncated valley has a bonding land of an area A2. A ratio of A1/A2 is less than 2. A distance D is between neighboring peaks, and a distance D is also between neighboring valleys. The corrugated layer is made from an initially flat sheet thickness of t. A first sheet layer is physically coupled to bonding lands of the truncated peaks. A second sheet layer is physically coupled to bonding lands of the truncated valleys.

Abstract: A sandwich structure (31) employs a core sheet (35) including alternating peaks (39) and valleys (41) therein. In another aspect, a sandwich structure includes at least one metallic core (35) and at least one adhesively bonded outer face sheet (33; 37). Yet another aspect of a sandwich structure has raised ridges (45) bridging between adjacent peaks (39) in a core sheet (35) in one direction but not in a perpendicular direction, thereby achieving different properties in the different sheet directions.
