Abstract
The authors of this paper researched a new honeycomb design and manufacturing method called 'oirigami honrycomb'. Resembling origami, kirigami honeycomb allows a single flat sheet of material with periodic slits to be folded into a honeycomb shape. The advantage of this method is that it can be extended to manufacture 3D (non-flat) honeycomb. This is achieved only by changing the crease patterns of original sheets. First, this paper describes a method for designing single-curved honeycomb panels using the kirigami technique. This method can facilitate arbitral W-direction (the mechanical direction in a normal honeycomb) shape changes in honeycomb structures. Then, a novel crease pattern conversion method is proposed, through which L-direction shape changes can be created in a Kirigami honeycomb. Finally, we introduce the developed relevant manufacturing equipment and provide some relevant prototypes.
