TETRAHEXAGONALE STUETZGITTERSTRUKTUR.

摘要

A lightweight, high strength moldable structure is comprised of a core having a plurality of interconnected cavities (12). Each solid-walled cavity (12) has a hexagonal base (24) so that the core of the structure has upper and lower surfaces. Each solid-walled cavity (12) has a unique tetrahexagonal shape in which a regular tetrahedron is located on top of and integrated with a hexagonal base. The walls (13) of the cavities may be solid or they may be defined by a series of support struts (63, 64) for an even lighter weight structure. The upper and lower surfaces may be covered by skins (14, 16) making it suitable for boat hulls, vacuum chambers, and aircraft.
