Research Paper On Keivlar
History
People have used many different things to protect themselves. It started out as
clothes and shields made from animal skins, and eventually, as we got smarter, we made
shields out of wood, and then metal. From there, metal was also used to create armor
protecting your body. After the 1500’s, when guns were introduced, metal armor became
much less effective, so they had to recreate their protection.
The first soft body armor was made in Japan, and produced from silk. This was too
expensive and not strong enough to sustain against newly made bullets and firearms, so
they kept looking for a better solution. After the silk vests came the flak jacket. The flak
jacket was made out of ballistic nylon and mostly focused on protection …show more content…

How it works
What Kevlar does and how it works is really simple. Kevlar is an extremely strong
compound used to reinforce different things. How it works is its strength, which comes
from its chemical structure. The chemical structure of Kevlar consists of many long chains

cross-linked to each other. It is highly resistant to everything other than UV light, which has
been known to break down the Kevlar. It is very lightweight and strong, normally used in
bulletproof vests worn by members of the military. It protects its wearer from almost
anything, and is also put on helmets.
The way it works is that liquid crystal forms in a straight line, unlike other
polyamides that are unordered. The inventor, Stephanie Kwolek, created a solution which
was spun into a polymer, and thus Kevlar was created to be one of the strongest things in
the world. Kevlar was made by Stephanie Kwolek, while she was working for DuPonti In
1964. She began searching for a lightweight, yet strong fiber that could be used to reinforce
radial tires.

Kevlar is very effective at stopping incoming forces, such as bullets, as long
as you have the correct kind of Kevlar for the situation. There are many different kinds for
different caliber of firearms. Kevlar is also resistant to ballistic fragments, much like the
previously made flak jacket. However it still does not deflect these pieces of ammunition
and still absorbs the force. With enough layers of Kevlar on the vest I believe It could
become resistant to almost anything and be one of the best forms or protection in the
world.

How would I improve it?
What I would do to improve the strength of Kevlar is to add more layers, a few extra
layers of protection onto the pre-existing form. This would, of course, increase the weight
of the vest, but it would also add to the provided protection tremendously. I would weave
the layers tighter, making it weigh less and provide more solid protection, rather than
having many open areas that could tear the fabric with enough force. On a vest I would add
sand bangs, hanging from the vest to protect the kidneys, which aren’t normally covered
