Multi-directional crushing characteristics of curved origami metamaterials with glass fiber-reinforced polyamides
Graphical abstract Display Omitted
Highlights A design method of curved origami metamaterial (CMM) with various origami creases is proposed. The CMM with glass fiber-reinforced polyamides are beneficial to strengthen its load-bearing level. The crushing behavior of the CMM with graded origami creases is more stable than that of uniform origami creases. The deformation mode and energy absorption efficiency of the CMM are sensitive to the configuration of origami creases.
Abstract This paper investigates the crushing characteristic of a novel curved Miura-ori metamaterial (CMM) with glass fiber-reinforced polyamides under multi-directional crushing loads. Based on the experimental test and numerical analysis, the deformation mechanism, crushing stress and energy absorption capability of the CMM are explored under multi-directional (0°, 10°, 20°, 30°) crushing loads. The progressive deformation mechanism of CMM with graded origami crease (CMM-G) is demonstrated, which follows its origami creases and exhibits high energy dissipation efficiency and load-bearing capability. There are worthy crushing merits in the CMM-G compared with CMM with uniform origami crease under multi-directional crushing loads, where the specific energy absorption of CMM-G improves by 24.93% under 0° crushing load. Moreover, the influence of geometric configurations of CMM-G is positive on crushing behavior. The deformation mode, load-bearing level and energy dissipation efficiency are sensitive to the origami amplitude A, the number of origami crease N z and gradient coefficient e of the CMM-G under multi-directional crushing loads. This paper illustrates the valuable mechanical performance of curved origami metamaterial with gradient and composite reinforcement, which opens wide potential applications as energy absorbers or load-bearing devices.
