The first images that come to mind when one thinks of a tank are typically a top-mounted cannon, treads, and of most importance to those inside, armor. The concept of a mobile vehicle protected by ...

June 26, 2019: Three years after it was realized the CMF (Composite metal foam) could provide superior protection against bullets and be much lighter as well, the theory was put to the test and it ...

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 ...

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 ...

A new study from NC State University suggests that a lightweight “metal foam” could prevent hazardous-material tank cars from rupturing during derailments, offering a potential safety upgrade as ...

The transportation of hazardous materials by rail could be made safer following a study at North Carolina State University with composite metal foam (CMF). Railroad tank cars are responsible for ...

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 ...

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 ...

A new study finds that composite metal foam (CMF) can withstand tremendous force – enough to punch a hole in a railroad tank car – at much lower weight than solid steel. The finding raises the ...
