Kevlar has improved the abrasion resistance tear strength, modulus, chip resistance and rubber strength. They are one of the engineering companies that meet the United State's standards and other countries' as well. For more information, see the related link.
No, Kevlar is not a hydrogen bond. Kevlar is a synthetic fiber made of a strong, heat-resistant polymer matrix. Hydrogen bonds are weak electrostatic interactions between hydrogen atoms and electronegative atoms like oxygen or nitrogen.
The repeating unit of kevlar is made up from two monomers. Benzene-1,4 dicarboxylic acid (A benzene ring with a COOH group on either end) and 1,4 - diaminobenzene (A benzene ring with an NH2 group on either end) When reacted in a condensation reaction, they form the repeating unit of kevlar; -CO-(Benzene)-CO-NH-(Benzene)-NH- With the oxygen molecules double bonded to the carbons. This then repeats over and over to create Kevlar.
Lumberjacks wear Kevlar for protection against sharp objects such as chainsaw blades and flying wood debris. Kevlar is a strong and heat-resistant material that can help prevent injuries while working in the dangerous environment of a lumberyard.
Yes, Kevlar is relatively expensive due to its high strength and durability. The cost of Kevlar can vary depending on the specific type and application, but it is generally more expensive than other materials like nylon or polyester.
The two monomers that form Kevlar are 1,4-phenylenediamine and terephthaloyl chloride. These monomers undergo a condensation polymerization reaction to form the long, stiff molecular chains characteristic of Kevlar.
Same reason anything is improved - to make it better. Stronger, lighter, more useful...

The protective plates, depending on the age of it, will be steel, ceramics, or kevlar.

One of the improvements that has been made to the calculator since the invention of the device is that calculators are much smaller now. Another improvement is that many of them are solar powered.

Performance improvements have been made in WinZip 7 including improved daily statistics performance, and a smaller navigation widget. A number of security fixes have been implemented to.
