Scale Dependence of the Mechanical Properties and Microstructure of Crustaceans Thin Films as Biomimetic Materials

Abstract

Two different shrimp species, R. exoculata and P. platyceros, were analyzed in the current study. The reduced modulus and hardness were measured by nanoindentation. There was a clear difference in the reduced modulus and hardness properties, which occurs because of the difference in the design of the shrimp exoskeleton. As shown in Figs. 4 and 5, there is a clear nonuniformity in the stacking density and thickness of layers across the cross section.
