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 ...

Composite metal foams (CMFs) are tough enough to turn an armor-piercing bullet into dust on impact. Given that these foams are also lighter than metal plating, the material has obvious implications ...

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 ...

Metal foams, also called cellular materials, are metallic bodies with interdispersed voids called cells. They have a reputation for high strength, low density, and absorbing impact. This combination ...

After years of development, metal foam that is lighter and stronger than steel and, according to its inventor, useful for anything made of metal—cars, planes, space shuttles, robots or surgical ...

Spongy metal sounds like a bit of an oxymoron, but it’s actually a real material that is capable of absorbing large impacts without damage. Metal foams have been around for some time, but new research ...

A startling new video shows a bullet fired from a high-powered rifle disintegrating upon impact with a marvelous new material. Part of a test conducted by North Carolina State, the video shows the ...

For 6,000 years, humans have been making things from metal because it's strong and tough; a lot of energy is required to damage it. The flip side of this property is that a lot of energy is required ...

Composite metal foam performs equally to or better than most conventional metals used in shielding materials, while weighing significantly less, according to new research. Reading time 2 minutes ...

A new study finds that novel light-weight composite metal foams are significantly more effective at insulating against high heat than the conventional base metals and alloys that they're made of, such ...
