Foldcore is an origami-like structural sandwich core which is manufactured by folding a planar base material into a three-dimensional structure. The manufacturing technology is open to a variety of base materials and a range of unit cell geometries is feasible. Foldcore can be made of metal, plastics (PP, PC, PA, PU, PS, PET, PEEK), duromere, composites, textiles, aramide, paper, foils and hybrids.
The mechanical properties of these folded structures depends upon the starting material, density, cell geometry and loads. As a rule, collapsible cores perform in the same range as a comparable honeycomb material. Compared to foams, woods and similar core materials of the same density, collapsible cores such as Foldcore offer significantly better stiffness and strength.
