Armor has been used in the military for a long period of time during the course of history, but is becoming more frequently seen in the public sector as time passes. There are many different forms and ways that armor is being commercially used throughout the world today. The most popular and well-known uses are body and vehicle armor. There are other commercial uses including aircraft armor and armored glass. Armor technologies Aramids Aramid fiber is the generic name of a group of synthetic fibers which are used in vehicle armor, fire equipment, tires, and bulletproof vests. The material has extremely high strength while still being flexible, and is very resistant to heat (it does not melt). In 2011 worldwide production of aramids was more than 60,000 tons. Para aramids The Para-aramid with the most production worldwide is Kevlar. It was commerciality introduced by Du Pont in 1972. In 1998 Kevlar accounted for 85% of the global market of para-aramid fibers. Kevlar is the material most often used in bulletproof vests. Different forms of Kevlar are anywhere from five to twenty times stronger than steel per weight. The disadvantages of Kevlar are that it degrades with exposure to UV light, is expensive to produce, and is difficult to shape. Meta aramids Meta aramids are aramid compounds that have a different molecular structure, giving them different physical properties to para aramid fibers. The most popular product of this kind is Nomex. Nomex has less strength than Kevlar, but it has extremely high heat, flame, ultraviolet, chemical, and radiation resistance. Meta aramids are commonly found in firefighting equipment, as well as military pilot suits and helmets. Dragon Skin Dragon Skin armor uses multiple ceramic and titanium composite two-inch discs that overlap, forming an armor that looks like scales of a dragon. This type of structure allows the vests to stay relatively light and flexible. Dragon skin has two main benefits over other types of body armor: It can take multiple hits from bullets and it doesn’t compromise the entire structure, and it deals with the blunt force of a bullet or projectile much better than most other types of body armor because the impact energy of a bullet can disperse over a larger area. In a test, using 5.56 mm, 7.62mm, and 9mm steel core, armor-piercing ammunition, and with more than a dozen shots, the dragon skin armor remains completely intact and
