HughPickens.com writes: Discovery Magazine reports that researchers at North Carolina State University have developed a super strong armor material that literally turns bullets to dust upon impact. The armor plating is made in part from composite metal foams, or CMFs, which are both lighter and stronger than traditional metal plating used in body and vehicle armor. The armor -- only an inch thick -- features a ceramic strike face, Kevlar backing, and CMFs in the energy-absorbing middle layer. "We could stop the bullet at a total thickness of less than an inch, while the indentation on the back was less than 8 millimeters," says Afsaneh Rabiei. "To put that in context, the NIJ standard allows up to 44 millimeters indentation in the back of an armor." CMFs are very effective at shielding X-rays, gamma rays and neutron radiation. Other applications include space exploration and shipping nuclear waste which both require a material to be not only light and strong, but also capable of withstanding extremely high temperatures and blocking radiation. A video shows a 7.62 x 63 millimeter M2 armor-piercing projectile that was fired using standard testing procedures established by the Department of Justice for evaluating armor types.
