This work illustrates the new method to manufacture the 3D shaped honeycomb cores. In usual methods, 3D honeycombs such as tapered or bended shaped cores require the difficult and high-cost processing, but this new method enables us to make arbitrary shaped honeycomb directory. In this paper, the basic concept of origami honeycombs is introduced firstly. They are made from single flat sheets with periodical slits like origami. Next, three types of simple 3D shaped honeycombs; tapered core, convex-curve core, nonconvex-curve cores are presented. These modified models are made by changing the folding lines and slits patterns of basic model. Finally, samples for these 3D shaped origami honeycombs are made by using the composite material.
