A: FROM MENTOR JOAN LUSK IN
RI
Kevlar is a so-called bullet-proof fabric. The polymer is
stronger than steel, weight for weight. It's made by Dupont:

The site lists all these applications-
Ropes that secure the airbags in the crucial landing apparatus
of the Mars Pathfinder
Small-diameter, lightweight ropes that hold 22,000 pounds
and help moor the largest U.S. Navy vessels
Shrapnel-resistant shielding in jet aircraft engines that
will protect passengers in case an explosion occurs
Run-flat tires that allow for greater safety because they
won't ruin the rim when driving to the nearest assistance
Gloves that protect hands and fingers against cuts, slashes
and other injuries that often occur in glass and sheet metal
factories
Kayaks that provide better impact resistance with no extra
weight
Strong, lightweight skis, helmets and racquets that help
lessen fatigue and boost exhilaration
And tells you where you can buy some. http://www.dupont.com/kevlar/protectiveapparel/where_to_buy/north_america_frame.html
But I didnt notice that it gave out the chemical
formula
theres an article on its structure in
the Journal of Chemical Education:.
Modern Sport and Chemistry: What a Chemically Aware Sports
Fanatic Should Know, by Guinevere A. Giffin, Steven R. Boone,
Renée S. Cole, and Scott E. McKay and Robert Kopitzke
J. Chem. Ed. 2002, 79, 772 and 896)
Embarrasingly enough, I found that reference by first finding
a correction: the printed copy had it wrong! See
