折纸是日本古老的折纸艺术，不仅是一种创造复杂形状的鼓舞人心的技术，而且是一种令人惊讶的强大方法，可以诱导非线性力学特性。在过去的十年中，折痕设计，力学建模和可扩展制造的进步促进了结构折纸材料的快速出现。这些材料通常由具有复杂3D几何形状的折叠折纸片或模块组成，并具有许多独特和理想的材料特性，如拉胀学，可调非线性刚度，多稳定性和冲击吸收。折纸中丰富的设计为设计这种折纸材料的性能提供了很大的自由度，折叠提供了一个独特的机会，可以有效地制造这些尺寸差异很大的材料。在这里，最近的研究折纸材料的几何设计，力学分析，实现性能和制造技术的不同方面的突出和未来的挑战进行了讨论。这些不同方面之间的协同作用将继续成熟和繁荣这个充满希望的领域。
Origami, the ancient Japanese art of paper folding, is not only an inspiring technique to create sophisticated shapes, but also a surprisingly powerful method to induce nonlinear mechanical properties. Over the last decade, advances in crease design, mechanics modeling, and scalable fabrication have fostered the rapid emergence of architected origami materials. These materials typically consist of folded origami sheets or modules with intricate 3D geometries, and feature many unique and desirable material properties like auxetics, tunable nonlinear stiffness, multistability, and impact absorption. Rich designs in origami offer great freedom to design the performance of such origami materials, and folding offers a unique opportunity to efficiently fabricate these materials at vastly different sizes. Here, recent studies on the different aspects of origami materials-geometric design, mechanics analysis, achieved properties, and fabrication techniques-are highlighted and the challenges ahead discussed. The synergies between these different aspects will continue to mature and flourish this promising field.
