Stephanie Kowlek Biography The most famous application of Kevlar is in bulletproof vests, which are made of layers of fabric woven from strands of the super-strong fiber. Patents In 1964, Stephanie Kwolek investigated a curious chemical solution in her DuPont lab; that polymer eventually became Kevlar, a fiber five times as strong as steel and lighter than fiberglass. Videos In its raw form, Kevlar is simply a fiber. The fibers are woven into textiles (like those used in body armor) or combined with other materials. Interview

Kevlar Containment Rings for Jet Engines
An airplane's jet turbines spin at a very great speed during flight. Occasionally, a piece of the turbine breaks. The shattered metal is moving fast enough to cut through the engine and, perhaps, the rest of the plane. Kevlar is used as part of a containment shield around the turbine that traps or deflects any stray pieces of engine. This video illustrates Kevlar's resistance to puncture in relation to jet engines.
