“…The uniformity of the plate and trabeculae in Zhang's biomimetic model is far worse than in Chen's model. There are only trabeculae in the core layer of Zhang's plate, and the trabeculae and plates are of uneven thickness; thus, there are substantial differences in the compression performance of these two biomimetic models [22]. The results demonstrate the superiority of the biological structure in this study in terms of the flexural mechanical properties.…”

“…Consequently, the authors developed an approach for producing FIHPs [21][22][23]. In a previous study [22], the characteristic features of honeycomb plates with upper and lower skins were skillfully used: after preparing a single-sided bonded honeycomb plate (SBHP) and long and short fiber-reinforced composite trabeculae, qualitative studies of the flexural and compression properties of SBHP were performed. The structural integrity of FIHP has been preliminarily confirmed.…”

In this study, the flexural properties of fully integrated honeycomb plates (FIHPs) were analyzed using experimental methods and finite element analyses. The effects of the perforated surface on the flexural properties of FIHPs were investigated by analyzing the flexural failure patterns and load-deformation curves of the FIHPs. The direction of the perforated surface has a significant influence on the flexural strength, and the structure exhibits different destruction patterns depending on the orientation. The experimental results indicate that although destruction occurs in the lower skin regardless of whether the perforated surface is up or down, the strength of the material of FIHPs can be optimized if the perforated surface faces upward because the chopped basalt fiber-reinforced epoxy resin composite material is strong in compression and weak in tension. A submodel of a thin honeycomb plate containing holes was developed to discuss these issues in detail. The analysis results suggest that the stress concentration around the hole is distinct and that cracks initially appear in this high-stress area. This paper provides some conclusions to support the better use of biological structures, and it offers some important theoretical support for the application of FIHPs in natural disaster emergency projects.

“…The density of the short-cut basalt-fiber-reinforced epoxy resin composite material was 0.85 g/cm 3 , the mass content of basalt fiber was 30%, and the length was 3 mm. (c2) are presented for comparison [26,28]. The stages have been renumbered for consistency.…”

“…These investigations led to a new type of lightweight bio-inspired composite consisting of a fully integrated honeycomb structure with fiber-reinforced trabeculae at the corners of the honeycomb cores. Based on this structure, we developed an integrated honeycomb technology [24,25]; we investigated the compressive and shear properties of the integrated honeycomb plates [26] and used simplified models to simulate the effect [27] of replacing the long fibers in the biological prototype with short fibers. However, there have been no previous reports related to the mechanical properties of fully integrated honeycomb plates (FIHPs) with sealed edge structures.…”

“…Based on the characteristics of a lightweight beetle forewing structure [5,6], Chen et al developed an integrated biomimetic honeycomb sandwich structure [7,8], which has advantages, such as cementing free, single cast forming, and excellent mechanical properties [6,9]. Currently, this plate is composed of reinforced basalt fibre epoxy resin composite material; the thickness of the honeycomb wall is approximately 2 mm [10].…”

This article proposes a new type of single-layer combined lattice shell (NSCLS); which is based on aluminum alloy honeycomb panels. Six models with initial geometric defect were designed and precision made using numerical control equipment. The stability of these models was tested. The results showed that the stable bearing capacity of NSCLS was approximately 16% higher than that of a lattice shell with the same span without a reinforcing plate. At the same time; the properties of the NSCLS were sensitive to defects. When defects were present; its stable bearing capacity was decreased by 12.3% when compared with the defect-free model. The model with random defects following a truncated Gaussian distribution could be used to simulate the distribution of defects in the NSCLS. The average difference between the results of the nonlinear analysis and the experimental results was 5.7%. By calculating and analyzing nearly 20,000 NSCLS; the suggested values of initial geometric defect were presented. The results of this paper could provide a theoretical basis for making and revising the design codes for this new combined lattice shell structure.
