ABSTRACT:
A structural panel comprises truncated polyhedral elements projecting from a base sheet, with the base sheet and truncation surfaces providing increased bonding areas for external face sheets. Mass produced, identical panels which are nestable for shipping and storage may be combined in an interlocking arrangement to form a combined panel which is nearly isotropic in its reaction to external loads.
