    Essentially a metal sponge consisting of hollow metal beads within solid metal, #composite_metal_foam (CMF) generally retains some physical properties of its base materials. While its defining characteristic is ultra-high porosity, CMF boasts 5 to 6 times greater strength as well as over 7 times higher energy absorption than previously developed metal foams. Typically created by melting aluminum around hollow metal spheres, it is impressively 70% lighter than sheet metal and 80 times more energy absorbent than steel. (...)

    “If tomorrow I can reach out to an investor in car companies and they want to put it behind the bumpers of cars, I’d be more than happy with that,” she says. “Or, if someone wanted to put it in body armor or vehicle armor, I would sure be delighted to help that happen. Any of these applications can save lives.”

    Professor Afsaneh Rabiei first developed metal foam for transportation and military use. Curious about the potential for nuclear or space application, Rabiei and her colleagues began researching the material further. In 2015, the team discovered CMF to be highly radiation-resistant.

    (...) Another metal foam developed at Cornell University is able to be transformed from one shape to another, and even has the potential to be used within biological systems — such as artificial knees, for example.
