Evaluation of Forming Methods for the Pre-shaping of Miura-Structures Made of Sheet Metal Materials

By applying the rules of technical origami, flat raw materials can be folded into cellular structures. This also includes semi-finished sheet metal materials. Such folded sheet metal structures can be used as multifunctional core materials for sandwich-structured composites, offering outstanding strength and stiffness properties at comparatively low component weights. Applications of this type of sandwich-structured composites comprise, for example, optically appealing claddings, heat exchangers and, in particular, lightweight constructions.
