Bouligand Structure

A Bouligand structure is a microstructure often found in naturally designed materials. It consists of fiberous lamella of a common direction, where adjacent lamella are progressively rotated with respect to the previous ones.[1] It enhances the strength and fracture resistance of materials, and is found in various natural structures including the dactyl club of the mantis shrimp, the cosmoid scale of the coelacanth, and many other stomatopods.
