In this study, structure-property relationships in the ironclad beetle (Zopherus nodulus haldemani) exoskeleton are quantified for impact-resistance. Impact resistant materials require constant innovation. In response, arthropod exoskeleton are researched to determine new design strategies. Determination of structure-property relationships in ironclad beetle exoskeletons provides a means to develop bio-inspired materials to be applied for impact-resistant material applications. Experimental study required examination of the microstructure through scanning electron microscopy and energy-dispersive X-ray spectroscopy (EDS) and measurement of the mechanical properties through indentation testing. The exoskeleton is a multi-layer material consisting of chitin in the form of a Bouligand structure. EDS showed the existence of elements such as those comprising chitin, calcium, manganese, and zinc. Mechanical testing was completed on the elytra and pronotum of the exoskeleton on the normal surfaces and on cross-sections. Future studies will involve the design of a novel bio-inspired material based on insights gained from ironclad beetle exoskeletons.
