Abstract:
1. A composite core panel having an upper core surface and a lower core surface comprising: a plurality of six-sided blocks of cellular material, and wherein each block has an upper surface facing the upper core surface of the core panel, a lower surface facing the lower core surface of the core panel, and four side surfaces extending between the upper surfaces and the lower surfaces of the blocks, a plurality of elongated primary strips of structural cellular material having a density greater than the density of the cellular material of the blocks, wherein the elongated primary strips have a pair of side surfaces, a pair of to surfaces, and a pair of end surfaces, wherein the primary strips are arranged such that the side surfaces of the primary strips are adjacent the side surfaces of the blocks and the to surfaces of the primary strips face the upper core surface and lower core surface of the core panel, wherein the top surfaces of the primary strips are flush with the upper and lower surfaces of the blocks, a plurality of elongated secondary strips of structural cellular material having a density greater than the density of the cellular material and extending in a transverse relationship to the primary strips, wherein the secondary strips have a pair of side surfaces, a pair of to surfaces, and a pair of end surfaces, wherein the end surfaces of the secondary strips are adjacent the side surfaces of the primary strips, and wherein the side surfaces of the secondary strips are adjacent the side surfaces of the blocks; and adhesive located between and adhesively attaching the side surfaces of the blocks and the side surfaces of the primary strips, between the side surfaces of the blocks and the side surfaces of the secondary strips, and between the end surfaces of the secondary strips and the side surfaces of the primary strips.
