According to New Atlas, researchers at the University of North Carolina, USA, obtained a coating against X-rays, gamma rays and neutron radiation. They succeeded in developing a new bulletproof material from metal foam. It has the same performance as a normal bulletproof shell, but is half lighter.

Through testing, some cases of bullets did not even leave dents on the material.
This material is based on the so-called composite metal foam (CMF). It is made by aeration through molten metal. The result is a foam mixture. It can then be cooled to form a light matrix and can easily arrange hollow metal spheres in it.
The resulting material is much lighter than the conventional metal bulletproof armor. But with the same durability. Through testing, some cases of bullets did not even leave dents on the material.
According to Afsaneh Rabiei, professor of mechanical and aerospace engineering, who led the study, if covering materials on military armored vehicles will help reduce the weight of the vehicle and thus improve fuel efficiency.
In the future, researchers also want to go further to produce CMF composite foam-based materials with higher efficiency. By combining CMF metal foam with ceramic plates, aluminum cladding and adhesive materials. At the same time optimizing the adhesion and thickness of the ceramic, CMF and aluminum layers, can make the coating lighter and improve the efficiency of the final armor layer.
