Folded structures are 3D regular relief configurations obtained from a plane by folding along a pattern.
Structures, made from specific material and having folded structure are called folded structures.
Advantages of folded cores:
Basic structure is a plane Z-crimp. Modifying Z-crimp, various shapes of folded cores with new properties may be obtained: with cellular structure, single or double curvature, curvilinear enveloping surfaces and areas of contact for bonding to the skins, and other properties.
