Scientists have invented a material called Composite Metal Foam, which claims to be able to withstand bullets from heavy machine guns or sniper rifles. The material is formed by the hollow metal ball system of lightweight foam, able to withstand 50 mm caliber bullets, heavy machine guns or sniper rifles are unable to put it through. And the weight is only about half of the steel armor, composite metal foam can withstand the impact of large-caliber bullets, general guns simply that it can not do. If you use the composite metal foam in armored vehicles or tanks, the weight is not only reduced, the defensive ability is also stronger, performance and fuel have been greatly improved.
The material is manufactured using a patented process and is made from a variety of metals, including steel and aluminum, and is filled with hollow bubbles that look like foam. The material also protects against high explosive shells, as well as shielding against fire, heat and many types of rays and radiation, among other features. In the experiment using armor-piercing shells, at a speed of 900 meters per second on the composite metal foam shooting experiments. The final results showed that the material can absorb 68-78% of the kinetic energy of armor-piercing bullets and 72-75% of the kinetic energy of bullets. The researchers also said that there is still room for optimization of the material.
The researchers also hope to further optimize the material to bring out its maximum capabilities. They would like to use it in the military to reduce the weight and increase the effectiveness of the defense. We can also continue to develop higher strength materials based on this material. In the future, the military will have better performance and reduce the casualties of soldiers. Their purpose is to stop the war bullets on the soldiers to bring the most fatal injuries, using them to continue to build bullets, we will build defense demolition material, to see who is stronger.
