2. Synthetic fiber developed by DuPont in 1965 Invented by Stephanie Kwolek Spun into rope of fabric Very high strength material 5 times stronger than steel at the same weight Many uses from tires, sails, armor, shoes, ropes, many others No known human effects en.wikipedia.org

3. Kevlar is a produced in a solution of monomers (phenylen-diamine) Condensation occurs creating a hydrochloric acid which is a byproduct Hexamethylphosphoramide was the used for polymerization (joining of long molecule chains) but due to safety reasons DuPont changed it to N-methyl-pyrrolidone and calcium chloride Patent have be created for this product Production is a very expensive process because It is very difficult using concentrated sulfuric acid There are 8 grades of Kevlar, K-29 the lowest Used in industry and the highest Kevlar KM2 used in Ballistics and resistant armor Spun into fibers Ultraviolet radian degrades Kevlar chemistrydaily.com/chemistry/Kevla

4. Kevlar is made up of hydrogen bonds Made up of Aramid fibers, which are heat resistant One Kevlar polymer chain can contain from 5 to a million bonds Each Kevlar unit contains 14 carbon atoms, 2 nitrogen atoms, 2 oxygen atoms and 10 hydrogen atoms http://ffden-2.phys.uaf.edu/212_fall2003.web.dir/adam_caswell/page1.htm

5. Fiber optics Produces high strength, which reduce mechanical stress on cables. Firefighter Gear Very strong and very fire resistance Body Armor Kevlar fiber is essential in combat, it provides a protection from pricing bullets and knifes Electronics Provides durable and portable products like, phones and computers Sporting Goods Sails the are lighter, stronger Racquets that have strings that dont stretch Boards that are lightweight and flexible Hockey sticks that retain shape and less likely to break Many other uses seen mostly in the reinvention of many products to be lighter and stronger http://www2.dupont.com/personal-protection/en-us/dpt/ua/vehicle-armor.html

6. How many different grades of Kevlar are there? What are two common uses for Kevlar? http://ffden-2.phys.uaf.edu/212_fall2003.web.dir/adam_caswell/page1.htm
