Abstract
A molded plastic core structure acceptable to numerous uses and characterized by high structural strength to weight ratio. The structure typically comprises a two-sided array of cell-like receptacles having inwardly sloping walls that form floors. Receptacles in one side are inverted relative to receptacles in the opposite side and are inter-nested between one another to minimize the volume of plastic used. The walls and floors can be circular, square or triangular in plan view. Where square or triangular, the walls include both major and minor wall sections alternatingly interspersed with one another. Two or more core structures can be joined to one another with the receptacles of one panel being aligned with the receptacles of the joined other panel to form closed, syntactic cells that give the resulting structure high enclosed volume to surface area and weight ratios.
