Kevlar: A Fiber has changed the War Industry

If anyone asks about bulletproof vests, armour, protective gear, space suits or Formula 1 helmets, the name Kevlar hits pretty much everyone's ears. The cause, Kevlar fiber, has changed the military industry and history. This fiber is widely used in the manufacture of protective clothing.

As science advances, scientists are constantly working to bring science fiction to reality. In its continuity, new technologies are being invented; new modern devices are being manufactured. The defense and military industry is no exception. Just as new state-of-the-art weapons are being developed. The same goes for various anti-weapon stuff. The most versatile material for weapon resistance is Kevlar.

What is Aramid?
Aramid is a special type of aramid fiber. It is made of synthetic textile material, which is very strong and light, and also resistant to corrosion and heat. It is a plastic strong enough to protect against bullets and knives. Kevlar is often described as "five times stronger than steel on an equal weight basis". Kevlar has a wide range of applications in military industry, body armor, body armor, automotive brakes, aerospace engineering, aircraft fuselages and ships.

Why were bulletproof vests and Kevlar born?
Since ancient times, people have participated in wars. Since ancient times, people have used armor to defend themselves in these wars. Let's start with iron, bronze or other alloys as armor. But in the 11th century BC, it was made from rhino hide, according to researchers.

This type of armor in China is considered the oldest. Greek warriors at that time also used a type of armor. It is known to be made of bronze and wax. It is difficult to say when the use of iron armor began. Later, in medieval Europe, elite warriors used heavy armor made of thin tin sheets for self-defense. However, as technology advanced, armor made of portable steel was invented in the mid-fourteenth century, providing warriors with head-to-toe protection.

Over the years, scientists have been developing sophisticated, advanced and powerful armor to withstand the onslaught of these sophisticated weapons. Then, a new fiber called Kevlar was discovered. This is often referred to as "five times stronger than steel on an equal weight basis".

How does Kevlar work together inside ballistic armor?
For example, have you ever seen a soccer player score a goal with incredible speed? Soccer ball hits the net of the goalposts at high speed. Although the football only hits part of the net, the entire net absorbs the ball's speed at this point. It will be easier to understand this with the example of throwing a stone into a pond.

football and stones

You throw a stone at one point, but the wave spreads to many places. The same thing happens if you throw a rock at a wall. (but the energy is absorbed invisible to the naked eye). The same thing happens with Kevlar armor. Kevlar absorbs the force of the bullet after it hits the bullet. As a result, bullets cannot penetrate it. If there is a ceramic ballistic plate it can also act as an absorber. Kevlar can be combined with other fibers to produce hybrid composites.
