ABSTRACT:
A panel having one or more dimple layers connected together by one or more reinforcing layers engaging ends of dimples on the dimple layer to create a cavity between the layers. The connection of the dimple layer and reinforcing layers creates an integral structural panel that can be planar by having identical heights of the dimples on the dimple layer to create a planar panel (flat) or nonplanar (curved) by varying the heights of the dimples on the dimple layer or through planar spacing adjustment. The panel can be modified in various ways such as by choice of materials and/or geometries of the various layers and/or incorporation of additional structural features.
