Integrated honeycomb structure of a beetle forewing and its imitation

The influence of processing holes on the flexural properties of biomimetic integrated honeycomb plates

“…2) was thought to be difficult to manufacture as an integrated body (Fig. 2a) [20,21]. It is this difficulty that motivated us to develop the honeycomb technology.…”

“…Furthermore, the fibers are continuous and are located in the trabecula-honeycomb plate organically ( Fig. 2b) [20,21]. The difficulties of manufacturing such structures by molding are obvious.…”

“…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].…”

“…The structural integrity of FIHP has been preliminarily confirmed. Because the biological structure is very complex, this structure cannot be precisely simulated at present [20]. There are two issues associated with our biomimetic samples: short fibers rather than long fibers are used in biological prototypes [18], and there are processing holes in the FIHPs [20].…”

There are two issues associated with our biomimetic samples: short fibers rather than long fibers are used in biological prototypes [18], and there are processing holes in the FIHPs [20]. The simulated effect on the compressive and shear mechanical properties when using short fibers rather than long fibers was investigated in a previous study [18].…”
