ABSTRACT:
A structural panel is of sandwich construction including upper and lower face sheets bonded to a central core. The latter is formed of a plurality of extrusion products disposed in abutting relationship, with each product being a unitary piece of longitudinally extending extrusion material having a matrix of interior walls which define the interior portion of each piece into a regular array of hexagonally-shaped apertures. The longitudinal axes of said apertures extend generally perpendicular to the planes of the upper and lower cover sheets. The resulting structural panel may be readily formed into a three-dimensional shape of enhanced strength.
