Abstract

This work presents techniques to design and manufacture morphing honeycomb configurations using kirigami-inspired cutting and folding techniques. Kirigami is the ancient Japanese art of cutting and folding paper that can be used to form a 2D sheet material into a 3D cellular structure. The honeycombs developed in this work differ from traditional cellular structures because of their reduced density and variable stiffness. The stiffness is dependent on the loading direction and on the type of loading, and this directionality is ideal for 1D morphing applications. Using kirigami techniques also allows actuators and geometric features to be embedded into the honeycomb to control morphing. Work has so far focused on characterising the effect of unique new geometry features on the mechanical properties of the structure, using Finite Element Analysis. The work presented in this paper focuses on developing the honeycomb’s morphing capability; we present techniques for manufacturing honeycombs with a functional shape, and analysis methods to predict the honeycomb’s morphing shapes.
