History
The first bullet proof armor was invented in 1897 by Korea and the Japan, it was made
of 30 layers of silk, which in that day could stop a black powder bullet it was nicknamed “soft
armor.” But then when firearms became more powerful it became useless. So a priest from
Chicago made it better by weaving 1.6mm steel plate between four layers of silk, he proved it
was “bullet proof” by having a man shoot at his chest from 10 paces (25 feet) away with a 44.
Caliber handgun, when it hit him he said he only felt a tap. So the inventor tried to make a life
off of his new vest. But sadly it never came true, because the military found that that the vest
was too hot to wear and was too expensive to make because of the amount of

Over many years it has evolved from silk and steel and then to ballistic armor which was
used during the Vietnam war, it was used mostly for shrapnel from an explosive but against a
gun it wasn’t very effective. Next was Kevlar it is the most recant and mostly used material
today, it is used by the military and police. But today scientists are working on new materials
for bullet proof armor, the first idea Is by mixing spider silk with goat DNA, it is called Biosteel. It
brings the fibers together to form a super strong yet light armor. The second idea is to coat
Kevlar in non-toxic nano-particles of silica to create a flexible but protective vest to stop bullets,
knives, and sharp shrapnel from grenades or explosives. (Lammle, 2010)

An example of a type of armor is Kevlar its material is made of a super strong plastic

The vest stops the force of the bullet from hitting you and going into you, it will disperse
the bullets energy across the entire Kevlar panel. If this didn’t happen the bullet would hit you
and cause serious damage to the area you were shot in. So that is the reason they make the
entire vest in one piece, so it can take that force of energy from the bullet and make It spread
throughout the vest. (company, 2016)
How effective is it?
Kevlar is what soldiers use today, they can stop some handgun bullets. Such as a 9mm
which has a smaller amount of kinetic energy and a lower velocity, but with a higher caliber
handgun such as a .44 magnum, it has more weight to the bullet which means a larger amount
of kinetic energy and a higher velocity, so you would need up to 30 layers of Kevlar. (Allred,
2015)
How would I improve it?
The improvements I would make would be to make a material that was made of a
strong medal that stops bullets, then I would mix it with a flexible compound to make the

fiber and Kevlar for military applications. “But the frame and design of the InvinciBull helmet
“This variation has a design of a smaller breach that fired a cartridge of 76.2x585R, allowing a breach that will automatically open after the firing of each cartridge” (Ordnance, T. O, 1920). This was an innovative concept that allows the firing of multiple rounds at a greater rate to help with the adjustment needed when firing at an aircraft traveling at a high velocity, attitude, and altitude. “The muzzle velocity of this weapon firing a 15-pound shell, with either shrapnel or explosive charge, is 2,400 feet per second” (Ordnance, T.O, 1920). The maximum
fire, due to the bolt-action mechanism. It was also designed to be used with a bayonet.
Captain John Norton of the British 34th Regiment in 1832 invented the cylindro-conoidal bullet. This was a large step in the gun making industry. This is because it has a hollow base, the hollow base allows the bullet to expand mid-air causing a larger wound in the victim. (https://en.wikipedia.org/wiki/Cylindro-conoidal_bullet) This model was worked on by a man called Claude Minnie.
In a Army Research Lab in North of Baltimore scientist are try to make the next evolution of warfare innovation. They are probably going to use liquids to make there be less injuries and it will soften the empact. They also want to prevent the whiping of their heads when it hits surface. They think that the equipment will do the same jobs as they
Hiram Maxim was the inventor of this fascinating weapon who created it in the year 1884. The machine gun was first seen and used by the British in 1885. Machine guns gave inspiration to many countries in creating their own version of the gun by making improvements and trying to maximize the number of rounds it can fire within a certain amount of time. Even though the British were the first to bring out the bad boy, the Germans quickly produced more than 12,000 machine guns which was more than what the British and French had combined. The first machine guns were seen at the start of the war in the Western Front in 1914.
The history of firearms begins in China in the ninth century where, huo yao, the world’s first gun powder was discovered; it was created by mixing charcoal, potassium nitrate and sulphur into a fine powder. Historians are prone to recognizing tenth century Chinese fire lances, a spear-like weapon combining a bamboo tube containing huo yao and projectiles tied to a Chinese spear as the first firearm. In the year 1320, Gun powder was developed into a specific formula, 15% charcoal, 75% potassium nitrate and 10% sulphur. It was developed for the
The material used
Bulletproof vest are made of either ceramic materials, layered Kevlar, metal plating, tensil liquids or a variety of other materials depending on the calibre of the weapon being shielded against. Small hand guns with low power will be effectively protected against by vests made of Kevlar fabric while higher calibre weapons will require more protection. Hand grenades and shotguns may require metal plated vests. (“What is a Bulletproof made of”).
Since this burgonet is created out of one sheet of steel, it allows the entire helmet to have a unified, highly polished look. This further contributes to the elegant and simple shape of the overall helmet.
Kevlar is a strong plastic that can resist bullets, knives and harmful chemicals and was invented by accident. Since it was invented, it has been used in many different kinds of protective gear. This plastic has absolutely changed the way we go about warfare, and we even use reinforce material such as car and bike tires.
I found a video that shows an example of early firearms piercing through plate armor.
A rifle bullet is longer and skinnier, whereas a shotgun shell is shorter and thicker.By just looking at the two different types of ammunition, one may think that the shotgun shell is more powerful, but it actually depends on the caliber and the gauge. Caliber is what a rifle bullet is measured by, and shotgun shells are measured by gauges.The casing of a rifle bullet is made of brass because it is resistant to corrosion while the actual bullet inside of the cartridge is made of lead. Steel is sometimes used to make bullet cartridges too because it is less expensive than brass but it cannot be reused like brass can. Shotgun shells are constructedof a plastic hull with a brass heading. In the inside of the shot gun shell there is what is called wadding and shot. Wadding is material used to separate gunpowder from the shot, and shot are little balls made ofany number of metals, including lead, steel, bismuth, tin and zinc. When shooting a rifle, the cartridge only has a single bullet or projectile, but shooting a shotgun results in multiple shot pellets released from the hull and causes a pattern. Ranging several miles, a rifle bullet can travel more than 3000 feet per second when a shotgun only travels about 1100 feet per second. Maximum range for a shotgun is only a few hundred
Made of Safariland’s thermo-formed plastic (SafariLaminate), the holsters retain their shape even after the gun is drawn, facilitating safe and quick draw and reholstering.
BulletSafe vests include woven high-density polyethylene, which is the identical material commonly used by security and police departments. The material is flexible, not a plate of armor. BulletSafe is comparable to other vests like Safeguard, BulletBlocker, Second Chance, GH Armor Systems and Point Blank. DragonSkin material is different and is comprised of a number of small hard plates which overlap similar to scales. The idea is to produce a flexible armor that is hard. Our vests consist of soft armor along with a flexible ballistic material. DragonSkin was created specifically to protect combat soldiers from rifle fire. The design of our vests is to protect users against bullets from handguns which are most common in crime situations. We provide ceramic ballistic plates to protect against rifle rounds and they are not flexible. They come in 10 X 12-inch sizes and are fitted into the plate pockets at the front and back of the BulletSafe
