You have a new low-weight-high-impact body armor! Well Kevlar is a bit like thousands of stiff fishing nets all laid on top of each other. A fast-moving projectile like a torpedo will hit them and then all its power will be rapidly dissipated and dispersed through the nets causing the torpedo to slow down and never reach the target i. The same is true of an incoming bullet. The more layers of Kevlar the more likely it will protect you.
Kevlar jackets are also not so effective with bullets fired from Assault rifles because they are traveling three times the speed of sound, way faster than those from a handgun. And that speed can help the bullet breakthrough the layers of the Kevlar. Now you might call THAT a full, metal jacket! This is because the heavier, thicker plates are designed to withstand larger rounds while the typical plate that is used for everyday wears, is lightweight and thin.
When a bullet comes into contact with the plate, the fibers absorb the impact and disperse the energy throughout the plate. When body armour was first used, the fact that the energy needed to be dispersed was not known. Many people were protected from the actual penetration of the bullet, but later died from the internal injuries they sustained from the impact of the bullet.
Bullet proof vests that are worn today are designed to take the impact and disperse it. The vests provide protection for the level they are designed to withstand.
It is important to be sure that you are wearing a vest that offers the right protection to suit your needs. A vest that is designed for small ammunition fire will not have the ability to disperse the energy that comes from a larger round. This means that the round could pass through the vest or the impact could cause internal injuries to someone.
The proper amount of the fabric layers is determined by testing against various types of handgun and rifle ammunition and matched against known threat protection standards. Each threat protection level is matched against a particular type of threat like handguns, rifles and even armor piercing ammunition. At the highest threat protection levels the Kevlar soft armor panels might be supplemented by ceramic hard armor plates.
A few threads may break but not enough to create a path for the bullet. The energy of the bullet is then dissipated outward instead of punching through the fabric. Save my name, email, and website in this browser for the next time I comment.
