Afsaneh Rabiei, a mechanical and aerospace engineering professor at North Carolina State University, who has spent her career working on composite metal foams, or CMFs, has developed a lightweight metal foam which can turn speeding armor-piercing bullets into dust in the blink of an eye.
In a dramatic video of her creation, a 2.5cm-thick sheet of the foam is shown stopping a 7.62 x 63mm armor-piercing rifle bullet dead in its tracks, exploding it into dust on contact.
The revolutionary material has applications in a number of areas, from the battlefield to space exploration and nuclear waste storage.
