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".

When did Stephanie kwolek create kevlar?
Stephanie Kwolek invented Kevlar in 1965 while working as a chemist at DuPont. Kevlar is a strong and lightweight synthetic fiber that is well-known for its use in ballistic protection and other high-strength applications.
What is kevlar armor?
Kevlar armor is a type of body armor made using Kevlar fabric, a strong synthetic fiber. It is designed to provide protection against bullets and shrapnel by dispersing the energy of impact. Kevlar armor is commonly used by military personnel, law enforcement officers, and in personal protective equipment.
Where was kevlar invented?
it comes from a UFO that crahed on earth in Roswell, New Mexico according to the records
What are Kevlar's properties?
Kevlar is a man made organic fibre that it is extremely strong and tough. Indeed, it is up to five times stronger than steel. When submerged in water, Kevlar can become up to 20 times stronger than steel. It can also withstand temperatures up to 300°C while still retaining its strength properties. Even at -196°C, Kevlar shows no signs of loss of strength. Almost all solvents are ineffective at corroding Kevlar except some very powerful acids. Kevlar, however is known to degrade when exposed to UV radiation.
What did Kevlar make?
Kevlar is a strong synthetic fiber used to make body armor, helmets, tires, and other protective gear due to its high tensile strength and heat resistance. Its discovery revolutionized the field of personal protective equipment.
How strong is kevlar?
it is very week
What is the usefulness of kevlar?
Bullet-proof vests are made of Kevlar as are motorcycle re-enforcement pads. Kevlar is extremely strong weave of synthetic fibre which has the added feature of being flexible.
How do you dispose of kevlar?
Kevlar is a strong synthetic fiber that is not biodegradable, but it can be recycled. Check with your local recycling facility to see if they accept kevlar, or contact the manufacturer for proper disposal methods. Avoid burning kevlar as it can release toxic fumes.
When did Stephanie kwolek create kevlar?
Stephanie Kwolek invented Kevlar in 1965 while working as a chemist at DuPont. Kevlar is a strong and lightweight synthetic fiber that is well-known for its use in ballistic protection and other high-strength applications.
Can magnets react to kevlar?
No, magnets do not react to Kevlar because Kevlar is not a magnetic material. Magnets only attract materials that contain iron, nickel, or cobalt. Kevlar is a strong and heat-resistant synthetic fiber used in body armor and other protective gear.
Why do lumberjacks wear 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.
What is the strong fiber manufactured by chemicals?
The? There are hundreds of strong fibers made from chemicals...but we'll be easy and say kevlar.
Who invented the kevlar vest?
Stephanie Kwolek, a chemist at DuPont, is credited with inventing Kevlar in 1965. Kevlar is a strong synthetic fiber used in protective gear such as bulletproof vests. Kwolek's discovery has saved the lives of many people in law enforcement and military fields.
Is kevlar a hydrogen bond?
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.
Why are kevlar they used?
Kevlar is a very strong man made fiber. Although flexible it is stronger than steel. It is one of several fibers used to make (among other things) body armor. Strong, lightweight, and flexible.
What is kevlar armor?
Kevlar armor is a type of body armor made using Kevlar fabric, a strong synthetic fiber. It is designed to provide protection against bullets and shrapnel by dispersing the energy of impact. Kevlar armor is commonly used by military personnel, law enforcement officers, and in personal protective equipment.
Why are kevlar gloves considered useful?
Kevlar gloves are important because they can provide excellent protection from work accidents. The reason Kevlar is used in the military is that it is very strong and can protect you from certain dangers that would otherwise be fatal. This is the same reason it can be useful in hard labor careers.
