Kevlar is poly para-phenyleneterephthalamide. That structure has a benzene ring that has a carbon chain on each opposite end ("Para") in a repeating fashion. So, it is like a strand of a rope.
The strands are held together tightly by hydrogen bonding between the amide (carbonyl (C=O) with an amine (NH) on one side) and by stacking interactions between the benzene rings and (a little bit) by dispersion forces.
So, since the strands hold on tightly to each other, it is chemically "tightly woven".
Kevlar is a very dense polyamide. It has a high tensile strength, making it useful in several ways, such as bullet-proof vests.
it makes you poop it makes you poop
Kevlar is not an element. It is a combination of elements, namely carbon, nitrogen, oxygen, and hydrogen. it is highly flammable. it makes up twaron, which is a substance used to make lacrosse sticks.
No, Kevlar is an insulator.
what is the Kevlar stock symbol
It depends on the rating of the Kevlar.
kevlar 49 is harder than steel
She created kevlar in 1965
1927 kevlar was invented by stephanie kwolec
Yes, Kevlar is a synthetic material.
Nobody makes ceramic hockey sticks (and I would wonder why if they did - ceramic is not the best thing to hit other stuff with), so kevlar/carbon fibre is the only answer.
Rarely everyday things are made from kevlar; I saw boots from kevlar but very expensive.
Kevlar was discovered in 1965 by S. Kwolek and his group.
Yes, kevlar has hydrogen intermolecular bonds.
Yes, the salt makes it more dense.
Yes it does Stephanie Kwolek the creater of Kevlar invented the fiber.
Kevlar is used by people like the police and the army. Other people may use Kevlar to build strong and safe items.
Yes. you can get at Kevlar tungsten wedding rings http://madtungsten.com/product-category/kevlar-carbon-fiber-rings/
fats are so energy dense due to their lack of water
A raw egg is not more dense than a boiled egg.
There are actually multiple people who warrant credit for the invention of the Kevlar bulletproof vest. The DuPont corporation developed Kevlar material. Richard Armellino marketed a Kevlar vest called the K-15 in 1975 and Richard Davis the first all Kevlar vest in 1976.
