The Kevlar strands allow the tape to bend and flex more than six inches but not break, stopping terrorist munitions or Mother Nature's fury. X Flex tape protects soldiers in several ways.

Kevlar¿ fibers are based on poly-paraphenylene terephthalamide, a rigid molecule that makes it easier to realize a fully extended, or straight, chain configuration.

The construction includes stainless steel connectors with 400D Kevlar fibers reinforce the inner wiring for added strength and 1050D individual Kevlar strands add durability and protection.

This novel Kevlar fiber is stronger, meaning that its makers hope they can fashion body armor out of it that's thinner and lighter.

This new super material is a game changer for firefighters and soldiers who need protection. It's just as strong as Kevlar, but incredibly heat-resistant.

Manufacturers use very dense strands of Kevlar—500 to 1,500 filaments per strand of yarn—and weave it into a netting. Then they cover the weave with a plastic film.

Shares of DuPont de Nemours Inc. (DD) gained nearly 2% in Monday’s after-hours trading session amid reports that the company is looking to offload two of its heat-resistant fiber brands ...

A team of researchers has created a new kind of nanofiber that can extend to seven times its original length—and is tougher than kevlar, too.

Strands must "absorb massive kinetic energy before breaking," and are "10 times better than Kevlar," wrote University of Puerto Rico zoologist Igni Agnarsson in Public Library of Science One.

Kevlar worked in all of these scenarios (except for the shot at the edge of the vest) by utilizing interwoven strands of plastic polymers to physically block the ballistic trajectory of the bullet.

Silk strands were fastened to hooks in equipment that slowly pulled the fibers apart, and the scientists measured how much stress the strands could take before breaking.
