折纸技术实现了板材的独特机械性能，而无需额外的部件。在此，基于折纸技术的增强特性开发了自折叠波纹结构（SCS）。波纹结构用作高强度、开放通道夹层结构的芯材。对自折叠芯材的研究很少;因此，提出了一种设计概念，并评估了SCS的力学性能。首先，通过改变印刷参数（例如，线宽和线/折痕的数量），以导出结构模型。该模型有助于设计具有所需结构的SCS。之后，通过进行三点弯曲测试来评估SCS的机械性能，以确定与高刚度相对应的基本设计参数。此外，SCS可以堆叠而不占用空间，从而导致提高强度。通过喷墨印刷使用自折叠纸制造的这些SCS成本低且环保。此外，它们专门用于快速设计和制造，具体取决于应用。在此，提出了使用SCS作为新型智能芯，因为它表现出高的运输效率和刚度，而无需额外的组件。这篇文章的互动预印本可以在https://www.authorea.com/doi/full/10.22541/au.164915946.65764739上找到。
The origami technique realizes unique mechanical properties of sheet materials without additional parts. Herein, a self‐folded corrugated structure (SCS) is developed based on the reinforcing properties of the origami technique. The corrugated structures are used as the core materials for a high‐strength, open‐channel sandwich structure. Research on self‐folded core materials is scarce; thus, a design concept is proposed, and the mechanical properties of the SCS are evaluated. First, the structural parameters of the SCS fabricated by changing the printing parameters (e.g., linewidth and number of lines/creases), to derive the structural model, are determined. The model facilitates the design of an SCS with the desired structure. Thereafter, the mechanical properties of the SCSs are evaluated by conducting three‐point bending tests to determine the essential design parameters corresponding to high stiffness. Moreover, SCSs can be stacked without occupying space, thus leading to improved strength. These SCSs fabricated using self‐folding paper by inkjet printing are low cost and ecofriendly. Moreover, they are specialized for rapid design and fabrication, depending on the application. Herein, the use of SCS as a novel smart core because it exhibits high transportation efficiency and stiffness without additional components is proposed.
