| Abstract Scope |
Beetles provide a plethora of examples of architected defensive structures. One such example is found in the exoskeletal forewings (elytra) of the diabolical iron clad beetle. Lacking the ability to fly away from predators, this desert insect exhibits an extremely impact and crush-resistant elytra via complex and graded interfaces. Here, utilizing advanced microscopy, spectroscopy and in-situ mechanical testing, we reveal previously unreported and critical multiscale architectural designs within the exoskeleton of this impressive beetle, the resulting mechanical response and subsequent toughening mechanisms. Additional analyses of this cuticle highlights the multifunctional nature of this structure, which contains a system of modulated surfaces and a network of pores that appear to provide paths for water absorption, transport and likely self-cooling. The architectural insights obtained from the study of this non-mineralized composite could be applied as design guidelines for the fabrication of multifunctional, tough and light-weight engineered materials for use in multiple applications. |
