A manufacturing method of folded and straight corrugated plate structure printed by environmentally‐friendly polylactic acid filled with environmentally‐friendly paraffin wax is proposed. Experimental investigations are conducted to characterize the out‐of‐plane compressive behaviors, including stress–strain curve, deformation processing, failure mode, strength, and energy absorption. By filling paraffin wax, the out‐of‐plane compression failure mode of sandwich materials from buckling (corresponding to empty corrugated sandwich panels) to wrinkling or crushing, which greatly improves the strength. Due to paraffin wax and its interaction with composite origami core, the energy absorption capacity is significantly enhanced. The research shows that the half‐filled folded corrugated sandwich structure not only has excellent specific energy absorption advantages, the paraffin wax has excellent heat absorption and release performance, and the unfilled part is just used as a heat flow channel to facilitate the flow of heat. This work has created a new method for rapid preparation of lightweight sandwich materials with not only high specific strength and high specific energy absorption, but also thermal channels.

“…Apart from this feature, other benefits of origami-inspired designs are low cost, monolithic, and spatial systems with accessible fabrication processes in comparison to the conventional mechanisms. [14][15][16] Finite element methods (FEM) have been widely used in the simulation of soft robotics to forecast the behavior of deformable parts. 17 In various soft robotics applications, FE analyses of joint parts are conducted by defining compliant materials as linear elastic.…”

Delta mechanism is one of the well-known parallel mechanisms used in robotic applications. In this study, the trajectory behavior of a novel Delta mechanism, which was designed and fabricated using layer-by-layer origami method, is investigated utilizing the finite element method (FEM). The mechanism was modeled with the dimensions of the actual fabricated mechanism. The mechanism consists of four different materials where properties of two materials are extracted experimentally via the tensile testing process. The accuracy of our model was compared to the finite element simulations and the results indicated that the mechanism follows the given trajectory within 0.05 normalized root-mean-square (RMS) error with respect to the kinematic model. The impact of the fabrication and instrumentation errors on the trajectory was further analyzed using FEM simulations and the contribution of each factor on the error was categorized. This validated numerical model can be used in the future to accurately simulate the mechanics of origami-inspired mechanisms and to design new mechanisms.

“…This conclusion has limitations in some situations [ 43 , 44 ]. One of the main reasons is that composite materials have a greater design freedom than single materials, which can greatly enrich the design possibilities of origami structures [ 45 , 46 , 47 , 48 , 49 , 50 ]. We can show a few representative works, as follows: Utilizing nonhomogeneous strain and folding techniques, novel 3D composite structures were achieved [ 46 ].…”

“…Carbon fiber reinforced plastic (CFRP) origami tubes were designed, and their excellent energy absorption capacity was identified [ 47 ]. Most recently, Du and co-workers developed a fabrication strategy inspired by origami techniques; they combined analytical, numerical, and experimental methods to investigate the mechanical properties of origami-inspired carbon fiber-reinforced composite sandwich materials [ 50 ]. In addition, it can be seen from the above literature review that most of the existing works are limited to quasi-static or static research, and there are few works on vibration characteristics [ 51 , 52 ].…”

Although Miura origami has excellent planar expansion characteristics and good mechanical properties, its congenital flaws, e.g., open sections leading to weak out-of-plane stiffness and constituting the homogenization of the material, and resulting in limited design freedom, should also be taken seriously. Herein, two identical Miura sheets, made of carbon fiber/epoxy resin composite, were bonded to form a tubular structure with closed sections, i.e., an origami tube. Subsequently, the dynamic performances, including the nature frequency and the dynamic displacement response, of the designed origami tubes were extensively investigated through numerical simulations. The outcomes revealed that the natural frequency and corresponding dynamic displacement response of the structure can be adjusted in a larger range by varying the geometric and material parameters, which is realized by combining origami techniques and the composite structures’ characteristics. This work can provide new ideas for the design of light-weight and high-mechanical-performance structures.
