This video profile of Stephanie Kwolekmade after she won the Lemelson-MIT Lifetime Achievement Award in 1999celebrates her life and her work on Kevlar and other sophisticated polymers. It includes footage and historic photos of her childhood, early career, and later work.
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.
