Sandwich-like structural element having a densely packed tetrahedral open core structure

摘要

A sandwich-like structural element (100) is disclosed. The sandwich-like structural element (100) has a thickness and height smaller than the longitudinal length and has a longitudinally extending first element (101) with a face and a length smaller than the longitudinal length A second element (102) having a surface and having a thickness and height and extending in the same longitudinal direction as the first element, the second element facing the surface of the first element (101) And a second element. The sandwich-like structural element is disposed between the first element (101) and the second element (102), and the first element (101) and the second element (102) An open core structure (103) operatively connected, further comprising an open core structure comprising a plurality of closely packed tetrahedral structures (201).
