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.

A multi-layered, unbalanced, bonded sandwich panel having improved top load support capability per unit of weight, which comprises: (a) a core; (b) a multiple-ply top laminate for resisting compressive forces; and (c) a multiple-ply bottom laminate for resisting tensile forces, said bottom laminate

A multi-layered, unbalanced, bonded sandwich panel having improved top load support capability per unit of weight, which comprises: (a) a core; (b) a multiple-ply top laminate for resisting compressive forces; and (c) a multiple-ply bottom laminate for resisting tensile forces, said bottom laminate having the same number of plies as said top laminate; wherein said multiple-plies of said top laminate and said bottom laminate comprise unidirectional fiber and resin layers of varied areal weights applied to said core such that the total areal weight of said top laminate is greater than the total areal weight of said bottom laminate.
