Abstract

The truss core surpasses the honeycomb core depending on the tasks. The height of core is limited by press forming and so on. Therefore, we developed a method by folding mountain / valley lines like origami. The origami forming method has the feature that it can be done from paper to metal by the same method. By examining three-point bending tests, drop tests, and analyzing them, we show that the structure that space-filled with cores obtained by the origami forming method called ATCP will be a box for both excellent cushioning material and transporting. Moreover, we also show that the core structure obtained by this has excellent sound insulation performance.
