The invention relates to a novel load-bearing space lattice structure, lightweight construction elements comprising such structure, and a process for the preparation of such lightweight construction elements. The structure is characterized by comprising faces or edges of truncated octahedrons in a space-filling arrangement. Such structures have an optimum ratio of surface area to volume and can therefore be realized with a minimum expense of material. Lightweight construction elements containing such structures, e.g., as a sandwich core, are superior to conventional elements with honeycomb cores in terms of strength properties. For the preparation of such structures, it is proposed to assemble them from molded parts represented by the faces of truncated octahedrons cut in half and arranged in a space-filling manner.
