Kevlar¿ fibers are based on poly-paraphenylene terephthalamide, ... whereas other, less rigid molecules behave more like cooked strands of spaghetti. Thus, ...

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 and Twaron are tough materials, but there’s a bit of a trade-off to be made between strength, heat resistance and weight. Now, researchers have created a new nanofiber material that’s ...

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.

While Kevlar can absorb up to 80 joules per gram before it breaks, the new material can handle up to 98 joules per gram. ... They then twisted these strands into yarns.

The resulting strands are tougher than Kevlar—a synthetic component used in bulletproof vests. Compared to synthetic materials, such spider silk is a far more biodegradable alternative that may be ...

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.

For example, regular Kevlar is roughly 0.26 or .27 inches thick, and the new material could be as thin as 0.19 inches, says Hovanec. “It’s a noticeable decrease in thickness of the material.” ...

Bulletproof vests of the future may be constructed from an unlikely material: paper. In May a team of researchers announced a new “nanopaper”—made of tightly woven nanosize cellulose threads—proven in ...
