NIJ Level IIA (handguns) - This level of protection is becoming less and less common. Much of our research was done mainly through conversation directly with the manufacturers. PE body armor is manufactured by bonding Unidirectional UHMWPE (Ultra High Molecular Weight Polyethylene) fibers over a high-density PE sheet. There is no doubt when it comes to its ability to stop and subdue a bullet. There are two main materials used to create these hard bulletproof panels: Commercial Ballistic Steel and Ceramic. Soft Panel Bulletproof Panel (Level IIIA): The average soft panel weights between 1 and 2 pound. The process and materials used to produce PE armor plates are expensive. There are three main materials used to create these bulletproof panels: Kevlar, Twaron and Dyneema. The resultant fibers are used to weave super-stiff and high-tensile sheets or mats that are now called Kevlar. Despite being such a tough and strong material, Kevlar can be damaged by ultraviolet rays. Such conditions would compromise the effectiveness of PE armor plates. Dry cleaning, bleaching agents, and frequent washing can also reduce the tensile strength of Kevlar. You do not need to be a police officer. They are known to be the most composite materials that are strong and function extremely well. Click here for Delays. Recruits try on their bulletproof vests at the New York City Police Academy. The National Institute of Justice (NIJ) sets minimum performance standards for bulletproof protection in their 0101.06 Armor Protection Levels Standard.

You could make a wall bullet resistant by backing it with sheets of steel–which seems like a pretty cost-effective solution since, per square foot, steel is cheaper than bullet proof Kevlar… The most vital part of a bullet proof system isn’t the flashy ballistic acrylic transaction windows or the bomb-proof buzz-thru door. The body armor also comes with very precise instructions on how to properly clean it when need be. Some will extend that to as much as ten years. So long as the bullet threat is not above level III, PE armor plates will offer ample protection. Ceramic plates are fragile and you must take good care of them if you must have them. We use mattresses made of straw, cotton, foam or rubber and sometimes metal springs. PE armor plates are classified as hard body armor. Synthetic fibers are created with polymers — large molecules composed of … Is a bulletproof clothing really a thing? On the flipside, the immediate break up on impact helps to ensure the bullet is stopped. To protect against blunt trauma, Kevlar bulletproof vests are reinforced with steel or ceramic plates. Conventional 1/8-inch or 10 gauge cold-rolled steel–with its highly variable carbon content, and thus strength–cannot be used in a bullet proof system. Peer review under responsibility of China Ordnance Society. Because of the weight of hard plate (metal) armor, you almost never see this type of panel used in a handbag or a briefcase design. You should replace a ceramic armor plate if it gets cracked.

Having said this, the TSA state that the final decision is up to the officer at the checkpoint. Free Shipping. This makes them very tightly bound, hence the high tensile strength. As most bulletproof clothing employ NIJ Level IIIA protection, they are not certified to stop high velocity rounds from weapons such as an AR-15 or AK-47. One of the most impressive aspects about steel armor plates, it that they can handle multiple bullets at the same spot, unlike many ceramic plates.

The tests provide information on the distances the bullets can travel in a gel/Kevlar medium before they are stopped and to identify the resistance capabilities of Kevlar of different grams per square meter (GSM). NIJ Level IV (Armor Piercing Rifles) - This is the highest rated in the 0101.06 standard. It is mainly common with tactical forces who are facing rifle gunfire threats.
