"A composite aluminum announced in a new study this week borrows its structure from the Asian pomelo. When you´re trying remove them to reach the tastiness within, the peels of citrus fruits are a waxy annoyance. This is especially true of the pomelo, a type of Asian grapefruit. But while this thick peel thwarts hungry humans, it lets the pomelo take a pummeling. A 4-pound fruit can fall 30 feet and land without splitting open because its peel has a composite structure that absorbs the impact. And now, that fruit has inspired a new kind of metal."
