Abstract : This project is aimed to create lightweight sandwich plates and shells with an origami core. Thesestructures are similar to commonly used honeycomb sandwich structures except that the cores arereplaced 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 celldesign which eliminates humidity inclusion in the closed cells of a honeycomb; secondly, they canbe formed to naturally fit even doubly curved shapes without distortion; and last but not least, theirgeometry can be designed to obtained the required structural performances. Through extensiveanalysis and experiments, we have successfully demonstrated that a suitable selection of coregeometries can lead to significant increases in the structural performance, making such compositesideal for aircraft structures. Our research has paved the way for much broader utilization of suchstructures in aeronautics and aerospace industries.
