Fluid-Impregnated Kevlar Armor

by

Developments in the area of body armor have led manufacturers to improve the durability of existing materials allowing bulletproof vests to be lighter and stronger. Traditional bulletproof vests that are made out of Kevlar are created by layering Kevlar cloth on top of one another until a desired level of protection is reached. As the number of layers increase, the vest becomes more rigid and also heavier.

Fluid-Impregnated Fibers

In an effort to make bulletproof vests lighter, there are some individuals that are experimenting with a special sheer-thickening liquid. This liquid is the impregnated into the Kevlar cloth so that fewer layers are needed. When the fibers are hit by a knife or object, the fluids freeze into a solid state deflecting the object and once the energy has subsided, the material will once return to its fluid state.

While this type of product is beginning to be introduced into bulletproof vests, you can see the advantages of having a lighter, stronger bulletproof vest. These types of fibers are perfect for prison system personnel as they are more likely to get stabbed while on the job.

Bulletproof vests provide protection against a variety of bullets. To ensure that you have the right vest, make sure that it fits you properly, that you understand its rating, and that it has the proper label.

Essential Facts about Bulletproof Vests

by

Protecting yourself with a bulletproof vest is critical if you are employed in law enforcement, private security or the military. Body armor is designed to stop the bullet from penetrating your body, which will allow you to continue to do your job and to provide for yourself and your family. However, there are a few important facts to consider when purchasing a bulletproof vest.

The Different Materials Used to Make Body Armor

There are several types of materials that are used to create the bulletproof vests of today. Kevlar is a popular product that has been providing protection for many years. This material is created by spinning Kevlar thread together to make yarn that is then weaved into cloth. This cloth is then layered to create a Kevlar vest.

Spectra Shield is created by lining Spectra fibers into parallel rows. Once a layer is complete, a second layer is created which is then turned to lay perpendicular to the first row. These layers are then affixed with a special resin.

Concealable vs. Tactical

Depending on the line of work you are in, you may be required to purchase a bullet proof vest that is worn under your clothes. This type of vest will provide protection from small to medium sized bullets. There is also tactical personal body armor that is worn over your clothes, which will protect you from small to medium bullets, as well rifle bullets.

Size Does Matter

If you are purchasing body armor, then you need to make sure that it fits you properly.

Each bulletproof vest will have a rating that is assigned to it (Type I, IIA, II, IIIA, III and IV). These ratings indicate which type of bullets the vest will stop. If you are in a position where you may be fired upon by rifles, then you want to select a vest that has a Type III or IV rating. It is extremely important that you do not purchase a vest that does not clearly indicate what the rating is.

These are a few of the facts that you should consider when purchasing a bullet proof vest. By taking the time to determine the size, rating, material, and style of vest you require, you will be in a better position to select the right one.

Bulletproof vest – Concealable vs. Tactical Gear

by

Adequate protection of your body and extremities while engaged in dangerous lines of work is an important point to consider. To assist you with the right protection, body armour companies have created different types of bulletproof vests.

These vests are designed to stop a bullet from injuring the body, as well as provide protection from other projectiles that may potentially cause injury. When selecting a bulletproof vest, it is important to determine if you prefer to have a concealable or tactical bulletproof vest.

Concealable Bulletproof Vest

If you are working for a client that wants you to have the appearance of an ordinary individual, then a concealable bulletproof vest is the perfect choice. Manufacturers of these types of vests have created form-fitting, comfortable personal body armor that will blend well with your street clothes. These vests can be worn under dress shirts or jackets to allow you the anonymity that is required.

An important point to make regarding concealable body armor is that these vests have limited protection as a result of their concealable nature. The vests can have a rating of up to II or IIIA, which is the cause of this limited protection. A bullet proof vest that is a Type II can protect the wearer from various bullets that include .22, .380, 9mm, .40, and .357 Magnum. These types of vests are not able to protect the wearer from bullets that are fired from a rifle.

Although concealable bulletproof vests will afford the an individual with protection from small arms fire while also providing a concealed appearance in the general public, you may want to look into tactical grade vests for protection from larger caliber bullets.

Tactical Bulletproof Vest

A tactical bullet proof vest will provide the ultimate in protection. These vests can have a Type III or IV rating which provides protection from small arms fire (the caliber of bullets listed above), as well as protection from bullets fired from rifles. This type of body armour is much larger and can only be worn over clothing. The manufacturer of these vests creates loops and pockets that provide the wearer with storage to hold ammunition and other important items.

These body armor vests are traditionally worn by individuals that are constantly in tactical situations, such as SWAT and military personnel. However, an individual’s mobility is somewhat reduced because of the size of the body armor.

Concealable and tactical body armor will provide you with the protection you require. By determining your current needs, you will in a better position to make an informed decision about the level of protection you require.

Bullet Proof Your Career and Your Life

by

Recently, the National Institute of Justice published a report that indicated only 1/3 of all criminal justice agencies require their officers to wear bullet proof vests while on duty. Many police officers, security guards and other men and women who put themselves in the line of fire are not required to wear them unless they are on high danger tactical forces. The problem is that a routine traffic stop, DUI checkpoints, the serving of a warrant, extra jobs at the bowling alley or just being in the wrong place at the wrong time can make you a target of gunfire by the sheer nature of your outer uniform. Seasoned officers admit that you never know when a routine domestic situation or un-alarming call will turn deadly and that what you wear beneath your blues, both heart and body armor, are the two fragile components that can allow you to keep your own life in tact.

There is a good chance that your agency provides you will bulletproof vests. Before wearing your vest it is vital that you are fitted properly, rather than just ordered a size based on an approximate measurement. Gaps in the bullet proof vest can leave an opening for a stray bullet and can cause you to feel cumbersome when moving around. When a bullet proof vest fits properly, it will lie like second skin against your body and you will be able to easily adjust to the weight after you become accustomed to it. Additionally, after five or so years your vest may be outdated and the Kevlar threads can become weakened. It should be replaced. Other indications that call for a vest replacement are if you have lost or gained weight recently which has altered the size of your normal clothes. If your vest has ever been involved in a shooting or piercing incident, the vest should be deemed unusable and replacement purchased.

Bullet proof vests are not only affordable but come in a wide range of gauges to give you just the right amount of protection for your job. They also have a full and expanse line of tactical gear like bullet proof bags, trauma plates and other gear designed to give you protection in a high fire power situation so that you can walk away with your life. Israeli bulletproof vests produced with Israeli Defense Forces ensuring that their products will hold up to he most aggressive of stand offs. They can provide an entire force or team of security officers with the gear they need to remain safe as well as sell updated equipment to an officer that wants to protect himself. From a long line of bullet proof vests, body armor, bullet proof bags and even stop spikes, everything an officer needs to gain the upper hand is offered at reasonable costs with the highest level of safety and security in mind.

Bulletproof Products (Clothing, Bags)

by

Having the right protective gear can mean the difference between surviving a serious calamity and dying. There are many individuals that unsuspectingly come under fire who were not properly protected. If you are in an employment position that requires a certain level of protection, then you should consider some of the many bulletproof products that are available on the market.

You may already know that you can purchase body armor that can be worn under or over your clothes. Depending on the rating of the vest, you may be protected from many types of small arms fire, as well as bullets from rifles. However, there are additional products that can be purchased which protect you from specific arms fire and are functional for everyday use.

Bulletproof Bags

Individuals that require a lower degree of protection and do not want to or need to wear a bulletproof vest can purchase bags and briefcases that will provide them with the shield that they need. Typically, the bags that consumers can purchase will provide up to a Type IIIA rating which will stop bullets such as .22, .38, .357 Magnum, 9mm, .40 and .44 Magnum calibers.

When confronted with a situation where you may be fired upon, these bags open quickly to afford protection against an oncoming bullet. If you have purchased a briefcase, the case will open to 180 degrees, allowing you to hold the top and bottom portion of the bag as a shield. Other models of bulletproof bags may also contain additional layers that can shield the body from head to toe when it is opened.

These products are normally made out of Kevlar, which is a special yarn-thread that is woven into the garment to create a protective cloth. The cloth is then cut and layered into the shape of the product. There are also other bulletproof materials, such as Spectra Shield, that may be used to create other body armor products.

Bulletproof Clothing

Many companies have created clothing options for individuals seeking every day protection that prefer not to wear regular body armor. These companies have created jackets and other items that provide the same protection as the bags mentioned above. These jackets have the ability for extra plates to be added to increase the rating if the needed arises.

If you are considering the purchase of protective gear, then you should take the time to determine what you are needs will be. Bulletproof products that are discrete can provide you the protection you require without having the wear traditional body armor.

Body Armor Uses in Law Enforcement

by

The men and women that serve in law enforcement need to be protected on an everyday basis. These individuals are met with constant danger as they patrol the streets of our nation. Most police departments require that their patrol officers were some form of body armor as it reduces the chances of serious injury when they come under fire.

Patrolmen and Patrolwomen

In order to be protected against the threat of a gunshot, a patrolperson can wear a bulletproof vest that has a rating of Type IIIA. This particular type of vest happens to be the highest concealable personal body armor that is available today. While it is unlikely the officer is going to come under fire from a rifle, they are protected from various types of bullets, such as .22, .380, 9mm, .40, .357Magnum and .44 Magnum.

Since these vests are typically worn under the uniform, they need to be form-fitting so that the officer can move properly in them. If the vest is too big, the officer may be at a disadvantage should they need to discharge their fire arm as the vest may have shifted.

Tactical Officers

Every major city and town will more than likely have a special response unit. These highly trained individuals will handle situations that involve kidnappings, bomb threats and other hostile situations. The bulletproof vests that these individuals will ear will more than likely be rated Type III or IV. They will protect the individual for small arms fire as well as bullets from a rifle.

It is important to note that these vests are heavier than Type I through IIIA and they are more restrictive in their movements. This is because the vests need to withstand shots fired from rifles.

Corrections / Jail Personnel

Individuals that work in the corrections system do not typically have to worry about the threat of gunfire since the inmates are locked up in their cell and the only ones with fire arms are the guards. The real threat these individuals face are from stabbings. Inmates often create stabbing devices out of metal and other objects that they will impale the guard with.

To combat this threat, guards can wear concealable body armor that will protect against stabbings. There are two classes of vests (Edged Blade and Spike Class) with three levels in each class. The levels are based on the amount of energy the vest can stop, which is measured in joules.

Law enforcement personnel need to make sure that they remain protected at all times because there are individuals that are waiting to take advantage of them. By properly determining the risk of injury involved in your line of work, you will be able to select the appropriate vest that will meet your needs.

Personal Body Armor Info

by

If you want to protect yourself from bullets fired by terrorists or hidden enemies, wear bodyarmor. Personal Body armor, commonly known as ‘Bulletproof vest’, can save your life from bullets. Soldiers have been wearing armor for thousands of years to protect themselves from enemies. Body armor is widely used by military, police, and body guards all over the world. Why not by you? You can find excellent and unique varieties of these vests.

Body armor is a ‘bullet-resistant vest’. Body armor has a web of very strong fibers. When a bullet strikes it, the impact energy is transmitted to the vest from the bullet. The fibers absorb and disperse this energy causing the bullet to deform. The web is hard enough to deflect the bullet. To every action there is always opposed an equal reaction and so the armor stuff pushes out on the bullet with the same power or nearly the same force with which the bullet pushes in, so the armor is not penetrated. Additional energy is absorbed by each successive layer of material in the vest; until such time as the bullet has been stopped.

Fibers of Bodyarmor prevent the bullet from penetrating inside. The multiple layers of the vest work together like a web and thus a large area of the vest prevent the bullet from penetrating. This also disperses the forces. However this may cause blunt trauma resulting into some non penetrating injuries to inner organs of the body. Research is going on to find more suitable material so that a vest is constructed from a single ply of material.

Human flesh is soft and weak and bullets are solid and fast. Personal Body armor has proven very effective in saving men lives under different situations. Bulletproof vests of different design and strength are made for different purposed. For example, body armor designed to overpower rifle fire is of either rigid or semi-rigid construction, made metals and hard materials like ceramics. Because of its weight and bulkiness, it is not practical for routine use. It is more relevant for use for short periods of time in tactical situations. It is worn especially to deal with higher level risks. Today, modern generation of concealable body armor is available.

Armor protects your precious life and you can, as per your threat perception, choose out of a variety of levels designed to overcome common low or medium energy handgun rounds to a rifle fire.

Kevlar

by

One of the most significant achievements in the development of body armor was the invention of DuPont’s Kevlar ballistic fabric. Invented by Polish-American female chemist Stephanie Kwolek while working for DuPont, Kevlar was accidently invented. Ironically, the fabric was originally intended to replace steel belting in vehicle tires. In 1964, her group began searching for a new lightweight strong fiber to use for light but strong tires. The polymers she had been working with at the time, poly-p-Phenylene-terephthalate and polybenzamide, formed liquid crystal while in solution, something unique to those polymers at the time. The solution was cloudy, opalescent upon being stirred, and of low viscosity and usually was thrown away. However, Kwolek persuaded the technician, Charles Smullen, who ran the “spinneret”, to test her solution, and was amazed to find that the fiber did not break, unlike nylon.

Her supervisor and her laboratory director understood the significance of her discovery and a new field of polymer chemistry quickly arose, giving birth to the incredibly strong fabric we all know today that stop bullets.

Flak Jacket

by

The next generation of anti-ballistic bullet proof vest was the World War II “flak jacket” made from ballistic nylon. The flak jacket provided protection primarily from ammunitions fragments and was ineffective against most direct pistol and rifle threats. Flak jackets were also very cumbersome and bulky and hinder a soldier’s effectiveness on the battlefield.
