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
Abstract . Materials capable of armor penetration and prompt chemical energy release are desired for future weapon systems in order to better couple the kinetic energy of a projectile to its target. High-density metals used today such as tungsten are slow to react, and do not generate as much chemical energy as lower density materials,
For the past two years a conglomerate of trade associations, industry, government and academia have been collaborating on the world’s first operational 3D printed excavator. That project made a giant leap forward with the recent printing of a prototype that leveraged large-scale additive manufacturing technologies and further explores the feasibility of printing with metal alloys.
