Abstract
A multi-layered, unbalanced, bonded sandwich panel having improved top load support capability per unit of weight is disclosed. The panel has a core, to the upper surface of which is affixed a multiple-ply top laminate. Similarly affixed to the lower surface of the core is a multiple-ply bottom laminate. The top laminate is thicker than the bottom laminate and supplies increased compressive resistance, while the bottom layer has an enhanced ability to withstand tensile forces. The core is preferably a honeycomb core, and unidirectional, fiberglass epoxy prepreg lamina are favored for each ply.
