New metal foam armor turns speeding bullets to dust
[Iran Press TV] From shields and plate armors used by soldiers and warriors in the medieval era to bulletproof vests worn by security forces in the modern times, personal armor has traveled a long way through history to protect bodies from enemy’s piercing weapons through absorbing the impact and reducing or stopping penetration. As the latest in a new generation of armor materials, metal foam armor can marvelously stop speeding bullets by turning them into dust upon impact, making it the ultimate armor so far.The new armor was made just recently out of composite metal foams (CMFs), a new ultra-light, high-strength material of the metal foam family, to further protect people and soldiers alike from armor-piercing bullets. CMFs are also used in the aerospace, military, naval, automotive, medical and other industries. "We could stop the bullet at a total thickness of less than an inch, while the indentation on the back was less than eight millimeters. To put that into context, the NIJ (National Institute of Justice) standard allows up to 44 millimeters indentation in the back of an armor," said Afsaneh Rabiei, an Iranian-born professor of mechanical and aerospace engineering at the North Carolina State University, who has spent many years in the development of CMFs and investigating their unusual properties.
