“…The beetle's elytra protect its hind-wing and body from potential outside damage by limiting the transfer of external loads. Zhou et al 18 carried out experiments by corroding the surface layer of beetle's elytra to study the internal structure. The corroded elytra are shown in Figure 2(b), it can be clearly seen that the thin-walled cavity honeycomb structure inside the elytra and the hollow columns are on its wall.…”

“…17 It is found that the ceramic tile greatly improved the stiffness of the sandwich plate while heavily weakened bending performance of the structure. Wei et al 18 presented a tailor-folding method to manufacture the hexagonal honeycomb structures made of carbon fiber reinforced polymer. Through this rapid and low-cost manufacturing method, the sandwich structure of all composite materials could be obtained efficiently.…”

“…Different from other interesting bionic energy absorbing structures which inspired by bone [19][20][21] and wood, [22][23][24] the honeycomb column structure existing in the beetle's elytra, as a special bionic light energy absorbing structure, has also been studied deeply in recent years. The studies on the internal structure of beetle elytra mainly focus on the internal morphology observation 17,18 and mechanical test. 1,25 Chitin is the main component of the honeycomb multi-cell structure inside the beetle's elytra.…”

Because of the advantages of light weight, small size, and good maneuverability, the bio-inspired micro aerial vehicle has a wide range of application prospects and development potential in military and civil areas, and has become one of the research hotspots in the future aviation field. The beetle’s elytra possess high strength and provide the protection of the abdomen while being functional to guarantee its flight performance. In this study, the internal microstructure of beetle’s elytra was observed by scanning electron microscope (SEM), and a variety of bionic thin-walled structures were proposed and modelled. The energy absorption characteristics and protective performance of different configurations of thin-walled structures with hollow columns under impact loading was analyzed by finite element method. The parameter study was carried out to show the influence of the velocity of impactor, the impact angle of the impactor and the wall thickness of honeycomb structure. This study provides an important inspiration for the design of the protective structure of the micro aerial vehicle.

“…Ha et al studied the circular straight and tapered thin-walled conical corrugation bionic tubes from the inspiration from coconut trees to enhance energy absorption efciency [21]. A hexagonal bionic tube of hierarchical bionic structures from the inspiration of a beetle has displayed excellent SEA, peak force, and crushing efciency [22]. Te Stomatopod-inspired structures displayed attractive behaviour and resisted high impacts while mineralized prey for food [23].…”

The 2.5D (2.5-dimensional) structures are acquired to enhance safety and lightweight designs with better energy absorption in the aerospace and automobile sectors. Additive manufacturing (AM), which is practical to build suitable components in industrial and transportation applications, may produce these structures more efficiently. The current study aims to improve the 2.5D infilled structures mean crush force (MCF) and energy absorption capabilities. Under compression loading, the proposed novel nature-inspired 2.5D infilled structure is compared to six existing 2.5D geometries that are inspired by nature. These structures are made of cylindrical shells that are filled with various infill configurations and maintained at a consistent volume. Photopolymer resin is used as the material for the structures, which are created using a digital light processing (DLP) method under AM technology. The characterization of the constructed models was done under compressive out-plane quasi-static stress conditions. ANSYS numerical simulations have been carried out to confirm the dependability of experimental data. The impact of supporting ribs and infill designs on crushing behaviour is thoroughly discussed. Mean crush force (MCF) and specific energy absorption (SEA) under quasi-static compression loading are provided to the proposed unique nature-inspired 2.5D infilled structure to significantly boost crushing qualities, axial collapse, and energy absorption behaviours.

Reinforcing and toughening materials with light quality in engineered structures remains a challenge. In the biological tissues of numerous animal and plant species, efficient strategies have evolved to construct structures that have excellent mechanical properties. As a kind of biological structure with high-strength fiber, beetle elytron not only provides protection function for beetles, but also makes beetles light enough to obtain good flight ability. Because of these advantages of inner fibrous structure of elytron, the bionic investigation of beetle elytron has gradually become one of the research focuses in civil engineering and automobile anti-collision fields. In the present work, the honeycomb and tubes composed of fiber in the beetle elytra was analyzed, and a variety of bionic thin-walled honeycomb structures with curved hollow tubes were designed and modeled. The energy absorption ability of the bionic honeycomb structures with different types of tubes under impact loading were calculated by finite element software. The internal energy values and collapse processes of bionic structures were compared and analyzed at different crushing displacements. The parameter study, including wall thickness and impact angle, was carried out in the collapse time range from 0 ms to 8 ms. These results could be applied in developing crush-resistant materials in the field of automotive passive safety.
