Lightweight Metal Foam Makes Autos Safer
Almost half a million dollars invested by the National Science Foundation over the last 5 years has just yielded a space age material so light and strong that it makes a 28 mile per hour crash feel like a gentle fender blip at 5 mph.
Afsaneh Rabiei has invented a metal foam with such a high strength-to-density ratio that it could revolutionize the auto industry. She says it isn’t the first metal foam, but hers has tested out as the strongest, partly because it utilizes a metallic matrix to support the cell walls.
