5.Dataset on bending resistance and impact resistance of dactyl club of mantis shrimp-inspired sandwich structure

Three-point flexural tests were performed by computer control electronic universal testing machine (DNS-100). These three structural honeycombs were estimated for five samples at a constant speed of 10 mm/min respectively, then took the average value. Wecould also figure out the energy absorption that was calculated as the area integral of the corresponding load-displacement curve of specimens under bending tests. Geometry of bending samples had a featured size of 125 mm 46mmandhadanaveragethickness of 18 mm, and the support span distance was 70 mm.
