How metal foam would make cars safer in a collision

Caption

At 55 mph, replacing a conventional front rail with an equal-length, equal-weight composite metal foam (CMF) rail significantly reduced vehicle damage and predicted occupant head injury. By progressively absorbing crash energy between the bumper and chassis, the CMF front rail transmitted less severe impact loading to the passenger compartment.
