Bullet proof vests are becoming a must for every law enforcement and military personnel that are on a mission or on the field
. This is because they are likely to survive when shot if they are wearing a bullet proof vest. The truth is there are many gunshot attack survivors who will attest how effective these body armors are.
Kevlar and Spectra are the two commonly used materials in body armors.
Kevlar is made by the weaving of Kevlar yarn in order to create a cloth which will be used for making protective body armor.
The weaving pattern of the Kevlar yarn including the layering of the cloth into a vest design gives it the protection needed to stop bullets.
Another material that is being used on body armor is Spectra. It is created by aligning fibers parallel to one another and bonding them with a resin. The cloth is then placed in layers to attain the level of protection required.
The alignment of the clothing along with the alternating pattern of each layer at right angle along with the addition of resin and polymer sheets helps in making the body armor.
For both Spectra and Kevlar, it is the amount of layers being used is what determines its level of body armor and what possible rounds it can withstand.
Knowing this is highly important because the wearer will need to know what type of guns or rifle his body armor can withstand.
When a body armor is capable of withstanding shots from rifles, then it is likely that it can withstand shots from a handgun. The only downside to wearing such body armor is the increased weight which is due to the amount of layer used.
Testing body armors means that they meet the standard level of protection and each are rated and tested accordingly. The vests are tested on dummies in which they fire shots at. To pass the test, neither bullets nor fragments should enter the dummy's body.
