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.

建筑折纸材料：折叠如何创造复杂的机械性能

折纸是日本古代的折纸艺术，它不仅是启发人的技术来制作复杂的形状，而且还是一种令人惊奇的强大方法，可以诱导非线性机械性能。在过去的十年中，折痕设计，力学建模和可扩展制造方面的进步促进了建筑折纸材料的迅速出现。这些材料通常由具有复杂3D几何形状的折纸折纸或模块组成，并具有许多独特且理想的材料特性，例如，膨胀性，可调的非线性刚度，多重稳定性和冲击吸收性。折纸的丰富设计为设计此类折纸材料的性能提供了极大的自由度，而折叠则提供了独特的机会，可以有效地制造出尺寸迥异的这些材料。这里，重点介绍了折纸材料不同方面的最新研究-几何设计，力学分析，获得的性能和制造技术-并讨论了未来的挑战。这些不同方面之间的协同作用将继续发展并繁荣这个有前途的领域。
