Researchers have demonstrated a new type of vehicle armor made of composite metal foam (CMF), which can resist.50 caliber bullets and armor piercing rounds. Compared with traditional steel armor, the greatest advantage of CMF armor is weight reduction. composite metal foam (CMF) is a "metal foam", like a sponge, with many holes on its surface, which makes it much lighter than ordinary metals. However, do not belittle these holes. Suppose that a tank is coated with this metal foam outside, the hole in composite metal foam (CMF) can absorb the huge impact energy caused by ammunition, and help to reduce damage.
In addition, the test results also show that the thermal protection of composite metal foam (CMF) is stronger than that of stainless steel, and the heat conduction time is twice as long as that of stainless steel.
It is conceivable that future armored vehicle and tank operations will be more flexible.
