How do you stop bullets using the lightest material possible? This question has inspired a string of fascinating breakthroughs from material scientists in pursuit of advanced lightweight armor that ...

Foams are not typically known for their toughness and tend to be rather ethereal when touched. But a new type of metal foam has been shown to be so strong it is capable of turning even armour-piercing ...

Making a vehicle that’s completely impervious to bullets isn’t impossible, but it would be so bulky and heavy from its thick armor plating that it would barely be able to move. Unless you build it ...

Researchers at NC State have announced a breakthrough in vehicle armor that might one day help protect our military personnel and law enforcement around the world. The researchers have demonstrated ...

Scientists at North Carolina State University are preparing to bring to market a lightweight composite metal foam that combines strength, thermal shielding and both ballistic and radiation protection.

Composite metal foams, or CMFs, are tough — so tough that they can destroy an armor-piercing bullet on impact, Phys.org reported. Another one bites the dust: You can watch as a 7.62-by-63-millimeter ...

Metal foam tough enough to turn an armour-piercing bullet into dust could be used to create the next generation of body and vehicle protection. A team at North Carolina State University discovered ...

The above block of foam is less than an inch thick. A bullet shouldn’t have any problem punching through that, right? Wrong. Meet composite metal foams, one of the materials of the future. Metal foams ...

Scientists have developed a lightweight metal foam which can turn speeding armour-piercing bullets into dust in the blink of an eye. The revolutionary material has applications in a number of areas, ...

This article is based on a Science Friday interview and was originally published on PRI.org. What would Styrofoam be like if it were made out of steel? Afsaneh Rabiei at North Carolina State ...
