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 ...

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 ...

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 ...

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 ...

Researchers have demonstrated that vehicle armor using composite metal foam (CMF) can stop ball and armor-piercing .50 caliber rounds as well as conventional steel armor, even though it weighs less ...

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 ...

The spheres inside the composite metal foam absorb the energy of a bullet. (North Carolina State University) Foam might not seem a likely way to stop a high-speed bullet, but a North Carolina ...

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 ...

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 ...
