As composites practitioners well know, tooling for composite parts is a challenge. Metal tools are the most robust option and support rate production, but they need to be carefully engineered to match ...

Researchers have demonstrated a new metal matrix composite that is so light that it can float on water. A boat made of such composites will not sink despite damage to its structure. This first ...

Scientists at North Carolina State University have already had success using composite metal foams (CMFs) to stop bullets and block radiation. Now, they've determined that a new one should also ...

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 ...

Composite metal foams (CMFs) are intriguing materials, offering several big advantages over traditional solid metal. And while the welding of CMFs usually poses some challenges, it has now been been ...

Metal matrix composites (MMCs) are composite materials containing at least two constituent parts – a metal part and a material or a different metal part. The metal matrix is reinforced with the other ...

Researchers have developed a range of composite metal foams (CMFs) that can be used in applications from armor to hazardous material transport -- and they're now looking for collaborators to help ...

Professor Afsaneh Rabiei heads up the Advanced Material Research Lab at North Carolina State University where she is developing a breakthrough metal product known as a composite metal foam (CMF). The ...

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 ...

The multi-material part—a skeletal steel component overmolded with a carbon fiber-reinforced composite — reduces finished part weight by 40% vs. a legacy cast-iron design. Increased strength enables ...
