This video makes us confident: high-speed cameras immortalize an armor-piercing bullet 7.62 X 63 mm of an M2-fired from a close distance of about 5 meters, at a speed of 3,000 km per hour, against a special panel of the thickness of about 2 and a half centimeters-lose about 65 percent of its mass, thus ending up literally shatter.

The material developed by professor Afsaneh Rabiei, a mechanical engineer at North Carolina State University, is a special composite-English metal foam "composite metal foams" or CMFS-a cellular structure consists of lightweight solid metal and pores filled with air.
Here you can find the results of the study.
Its possible applications ranging from the scope of course war-bulletproof vests or linings for vehicles-spatial scope, the material has in fact proved resistant to X-rays, gamma rays and neutron radiation, a property which may also prove useful in the treatment of radioactive materials and nuclear-waste being the material capable of withstanding the high temperatures.
In short, we look forward to having the chance of metal foam wear coats even when it is very hot.
