Kevlar is 20 times stronger than
steel and is used in the manufacture of bullet proof vests. Follow a series
of clues on well-illustrated pages on the different aspects of Kevlar to determine

“Microworld” web site, which is designed for Grades 9-12, may prove
difficult for some students.

many uses at DuPont’s Kevlar Home Page.
