Claim:
A high strength low density panel comprising: a plurality of box shaped sections, each said box shaped section having an upper face opposite a lower face, said upper and lower faces each having a midpoint, said upper and lower faces each having four corners, said upper face further comprising a continuous band of material extending from each corner of said upper face to an opposite corner of said upper face through a point proximate to said midpoint of said upper face, and said lower face further comprising a continuous band of material extending from each corner of said lower face to an opposite corner of said lower face through a point proximate to said midpoint of said lower face; each said box having four corner edges, each corner edge extending from about each corner of said upper face to about a corresponding corner of said lower face, said corner edges each comprising a continuous column of material extending from said upper face to said lower face; each said box having a central axis running from a point positioned at about said midpoint of said upper face to a point positioned at about said midpoint of said lower face, each said box further comprising a central column of material positioned proximate and substantially parallel to said central axis; each box further comprising a plurality of void spaces, said void spaces having an interior, a base and an apex, said void spaces having a longitudinal axis extending from said base to said apex, said void spaces positioned within said box with said longitudinal axes of each said void space substantially parallel to said central axis.
