Abstract

A sandwich structure employs a core sheet including alternating peaks and valleys therein. In another aspect, a sandwich structure includes at least one metallic core and at least one adhesively bonded outer face sheet. Yet another aspect of a sandwich structure has raised ridges bridging between adjacent peaks in a core sheet in one direction but not in a perpendicular direction, thereby achieving different properties in the different sheet directions.
