Researchers at North Carolina State University have demonstrated a new composite metal foam (CMF) material that can stop armour-piercing .50-cal rounds from piercing armoured vehicles as effectively as steel, while having the advantage of weighing half as much. The discovery will allow military vehicles designers to develop much lighter armoured vehicles to the same safety
