Abstract : This project is aimed to create lightweight sandwich plates and shells with an origami core. These structures are similar to commonly used honeycomb sandwich structures except that the cores are replaced by a corrugated structure generated by folding sheet materials using origami techniques. The most noticeable advantages of the origami cores are that, first of all, they have an open cell design which eliminates humidity inclusion in the closed cells of a honeycomb; secondly, they can be formed to naturally fit even doubly curved shapes without distortion; and last but not least, their geometry can be designed to obtained the required structural performances. Through extensive analysis and experiments, we have successfully demonstrated that a suitable selection of core geometries can lead to significant increases in the structural performance, making such composites ideal for aircraft structures. Our research has paved the way for much broader utilization of such structures in aeronautics and aerospace industries.
