Abstract Scope |
Many fruits, like coconuts and pomelos, have protective exteriors that are remarkably tough and protect the plant’s seeds from impact. However, the largest fruit in the world, the jackfruit, has remained untouched by the biological materials community despite the fact that it falls from up to 70 feet and has been reported to exceed 100lbs in weight. Here, we report on the structure and mechanical properties of this novel biological material. The jackfruit skin bears irregular hexagonal protrusions that control crack propagation and delocalize damage, while the fruit’s interior has a highly aligned porous structure. Compact tension, freefall, drop tower, and small particle gas gun impact tests illustrate these failure mechanisms and show how this unique configuration improves damage control for this enormous biological projectile. We believe that these design motifs can easily be transferred to engineered systems and can readily be adopted by additive manufacturing techniques. |
