The choice of the ideal materials used in the protective armors depends on the level of protection levels. These armors are designed and fabricated using the combinations of ceramics, metals, polymers, fibers, and some composites. Several companies are competing with each other in the development of the lightest and most durable body armors.
Why Material Is Important in Body Armor?
Body armors or tactical vests are weighed up to 8 lbs, which are made of synthetic fibers like Kevlar, Polyethylene, etc. In previous times, body armors are extremely uncomfortable and bigger in size before the invention of synthetic fibers. But now, with the help of these materials, it has become less in size and stronger. These materials make the armor provide higher performance in protection. Considering the material used for the armor production can be varied with different levels of usage. So, it is important to select the right material for body armor according to your need.
Types of Material Used in Body Armors
Based on the sustainability of the vest, body armors are made from different materials. The best three materials are as follows,
Kevlar:
Kevlar is a strong fabric that brings a revolution in the history of making bulletproof armors. It works as an excellent anti-ballistic material. This material can absorb and spread out the energy of the bullet. Kevlar is light in weight and flexible enough to wear for a long time. It is used in the manufacture of rifle plates with less weight. These armor plates are stronger than steel and give much protection.
More layers of this material will give more protection. A typical bulletproof vest can have at least 8 to 16 layers of Kevlar and even up to 32 to 48. Being a strong and tough material, Kevlar can be damaged by UV rays. Frequent washing and dry cleaning of these Kevlar body armors can reduce the tensile strength of the material.
Steel:
Steel is the cheapest armor material, and it doesn’t need to be taken care of like Kevlar material. It is the heaviest material and harder to set in your body gives more uncomfortable. Even though, it is rigid, when the high-speed bullet hits the armor can have possibilities to pass through the plate. So, it is not used for a high level of protection.
Polyethylene:
Polyethylene is also a common type of plastic used in armor and plate production. These are rated by UHMWPE as the most durable thermoplastic ever produced. Polyurea ballistic plate are also made up of the composition of polyethylene with ceramics. These plates can stop the bullet when got hit in the same place without cracking or decreasing its effectiveness.
Conclusion
Choosing the right material that depends on the level of threat you are facing. Make sure it is comfortable for your need when you are wearing the right armor.
