In the Journal of Applied Physics, researchers explore an eggshell-inspired design as a potential spacecraft protection material. It may seem counterintuitive to use eggshells as a blueprint for strength, but they found that organizing water-filled aluminum eggshells into an array adds useful material properties when placed blunt side down between two aluminum impact plates. Rather than being concentrated within a single eggshell, the energy from an impact gradually dissipates through the material, allowing each shell to sequentially collapse and deform.
