Abstract : The basic Tetra-Core element consists of a series of tetrahedrons which are alternately inverted and placed such that they form continuous planes. Tetra-Core elements have been fabricated in various shapes, both flat and curved, using either filament winding or forming techniques. The report describes the basic techniques used in the fabrication process and the material properties.
