A revolutionary new material called Composite Metal Foam, or CMF, can pulverize enemy rounds and could even be used as an armor to protect tanks and other combat vehicles. Believe it or not, this ...

Composite metal foams (CMFs) are little-known materials that are beginning to show some big promise. Last year we saw researchers adapt these lightweight materials to stop various forms of radiation ...

A composite metal foam (CMF) material developed by researchers at North Carolina State University can stop ball and armor-piercing .50 caliber rounds as well as conventional steel armor, even though ...

RALEIGH, N.C., April 6 (UPI) --Armor piercing bullets are supposed to be indestructible. They never met metal foam. Materials scientists at North Carolina State University have been working with ...

Usually, it takes a lot of heavy, cumbersome metal to stop a bullet. Conventional body armor uses heavy steel or ceramic plates inside a kevlar vest to stop the massive kinetic energy of an ...

When designing armor capable of stopping a bullet, the two most important factors are weight and resistance to penetration, and they’re often at odds with one another. A thick steel plate can stop ...

Foam body armor? Even armor-piercing bullets cannot get through this foam. And the foam doesn’t just stop bullets. It destroys them…this foam decimates bullets into dust. North Carolina State ...

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 ...

While Kevlar is often used to protect law enforcement and soldiers from projectiles, it struggles to stop armor-piercing bullets. But now a type of composite metal foam (CMF) has been developed that ...

Stainless steel composite metal foam can replace rolled homogeneous steel armor with the same protection for one-third of the weight. According to the material’s inventor the material would make a ...

Metal foams are light and surprisingly tough. Actually, make that very tough: In this video, a composite metal foam turns an armor-piercing bullet to dust on impact, as if it were a piece of chalk.
