Abstract: 
kirigami arts have provided a more promising method for building multiscale structures, which can shape two-dimensional (2D) sheets into three-dimensional (3D) configurations by cutting and folding. Here, we first carried out a theoretical analysis of the mechanical properties of 2D honeycomb lattice structures and experimental verification combined with finite element (FE) simulation. Furthermore, a series of thick-walled 3D kirigami-inspired honeycomb (TW3KH) structures with different mechanical properties were designed and fabricated on the exploration and optimization of geometric parameters of 2D honeycomb structures. The investigations of folding feasibility, self-expansion, and self-folding performance experimentally showed that our designed four-dimensional (4D) printing structure had good programmability and shape memory capability and a large volume change ratio during shape change. Meanwhile, research on its compression deformation behavior found that the TW3KH structures can recover load-bearing capacity very well when the angle is positive. Therefore, these TW3KH structures have great advantages in space-saving smart load-bearing equipment.

哈尔滨工业大学冷劲松等 | 4D打印厚壁kirigami蜂窝结构的形状回复性能和承载能力

蜂窝结构源自自然界中的蜂窝。它是一种由规则的六边形单胞背靠背对称布置组成的结构,以其高比刚度/强度和能量吸收能力而闻名,引起了许多研究人员的关注,并已广泛应用于航空航天、运输包装、建筑承重和医疗植入领域。然而,一经制造,其结构不会根据应用的需要而改变,这极大地限制了其在某些特殊应用场景中的应用,尤其是在具有承重要求的智能空间可展开结构中。四维(4D)打印技术对于制造复杂结构更为灵活。并且,由于形状记忆聚合物(SMP)的特性,允许制备的对象具有可重编程性能,这些对象可以响应外部刺激回复其原始形状。这有望提高其在应用中的灵活性和适应性。
近年来,相比于折纸,具有更高自由度的剪纸(Kirigami)艺术为构建多尺度结构提供了一种更有前途的方法,其可以通过切割和折叠将二维(2D)板状结构成形为三维(3D)构型。然而,Kirigami原理的复杂性和对主动配置的需求通常会在实际应用之前带来许多不便。本研究将4D打印技术与Kirigami艺术相结合,设计了一种4D打印厚壁Kirigami蜂窝结构,有望应用于节省空间的智能承重结构中。
本研究首先建立了考虑粘弹性变形条件下的结构分析模型,并设计了具有不同拓扑角度的二维六边形晶格结构。该模型预测并分析了每个拓扑角对等效弹性模量(E)和泊松比(v)的影响。有限元分析和实验结果与理论预测吻合良好。基于对2D蜂窝结构几何参数的探索和优化,我们设计并制造了一系列3D厚壁Kirigami蜂窝(TW3KH)结构。利用4D打印技术制备的厚壁Kirigami蜂窝结构具有折叠后可自展开,展开后可自折叠得能力,并且具有良好的形状回复率和大的体积变化率,有望应用于节省空间的智能承重设备。同时使用ABAQUS软件通过广义Maxwell粘弹性本构模型(GMM)模拟了垂直编程结构的形状回复过程。压缩实验和有限元模拟研究表明形状回复前后的结构具有较好的承载性能。
