“…Microstructures and bio-structural design techniques of C. septempunctata provide important models that can be used to develop improved lightweight biomimetic composite structures (Chen et al, 2007(Chen et al, , 2008(Chen et al, , 2012. Many studies have been carried out on insect wings using AFM (Brukman and Carpick, 2006;Dokukin et al, 2011;Lin et al, 2013;Steffens et al, 2014), but there is little research on the morphology of ladybird forewings using AFM.…”

In recent years, the surface morphology and microstructure of ladybird (Coccinella septempunctata) wings have been used to help design the flapping-wing micro air vehicle (FWMAV). In this study, scanning electron microscopy (SEM) was used to verify the functional roles of the ladybird forewing and hindwing. Surface morphology and the cross-sectional microstructure of the wings are presented. Detailed morphology of ladybird forewings was observed using atomic force microscopy (AFM) and the composition of the wings was characterized using Fourier transformed infrared spectroscopy (FTIR). The ladybird forewing may possess different performance characteristics than the beetle, Allomyrina dichotoma. Additionally, the circular holes in the forewing might be important for decreasing the weight of the forewing and to satisfy requirements of mechanical behavior. Microsc. Res.

“…To overcome the weakness of multi-body forming honeycomb plates, the authors applied biomimetics [17] research methods [18] and found that the microstructure of beetle forewings is that of a fully integrated honeycomb plate (FIHP) with edge-sealing features [19,20]. Consequently, the authors developed an approach for producing FIHPs [21][22][23].…”

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.

“…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].…”

Shear Strengths of Different Bolt Connectors on the Large Span of Aluminium Alloy Honeycomb Sandwich Structure

This study investigates the shear capacity of aluminum alloy honeycomb sandwich plates connected by high-strength, ordinary, or self-tapping bolts. For that purpose, experimental tests and finite elements are carried out. The failure of a high-strength bolt connector is driven by bending deformations developed in the bolt that deform connection plate and pad openings. In the case of ordinary bolt connectors, stress concentration on the bolt shear surface causes a large shear deformation that finally leads to failure. In the case of self-tapping bolt connectors, the insufficient mechanical bite force of the screw thread yields the bolt misalignment and concentrates shear deformation. As a result, the high-strength bolt connector is the most efficient design solution. If the bolt hole edge distance is more than 1.5 times as much as the bolt diameter, the connection performance becomes insensitive to this parameter. The practical formula for evaluating the connector shear capacity is derived from experimental data.
