Eric Wetzel of the U.S. Army Research Laboratory and Norman Wagner, professor at the University of Delaware Center for Composite Materials, have worked on armor technology for a decade. One material ...

A revolutionary new armor relies on a liquid that hardens when something hits it, promising unprecedented protection while letting soldiers move freely, unrestricted by bulk and weight. Protection for ...

Rheologists have created a new way of bullet-proofing clothes using shear-thickening fluids. This shear-thickening liquid is actually a mixture of hard nanoparticles and nonevaporating liquid. Fabric ...

Kevlar and ceramic body armor can potentially stop a bullet and prevent the death of a soldier, but tends to be bulky and restricts movement. Certain types of armaments can also pierce Kevlar. Defense ...

New research by NIST and Georgetown scientists deciphers the mechanisms that cause the materials to switch between liquid and solid in response to stress. Oobleck's name is borrowed from a Dr. Seuss ...

Scientists at a Polish company that produce body armor systems are working to implement a non-Newtonian liquid in their products. The liquid is called Shear-Thickening Fluid (STF). STF does not ...

Air Force cadet Hayley Weir had an idea that turned out to be a game changer. "It was just the concept of going out there and stopping a bullet with something that we had made in a chemistry lab." The ...

Progress is being made on exoskeletons for US special forces. The exoskeletons are designed to increase strength and protection and help keep valuable operators alive when they kick down doors and ...

It expands, it contracts, it gets stronger, it lets up — it reacts to changing conditions in formidable and comfortable ways. And the adventures of shear-thickening fluid, invented by University of ...

A gooey substance normally wouldn't seem like it could stop a bullet, but an Air Force Academy cadet has created just that. Cadet 1st Class Hayley Weir's interest in bullet-stopping materials was ...

Researchers using a high-speed camera have captured the moments a fluid reacts like a solid, through a new method of fluid observation under pressurized conditions. They examined fluids that have a ...
