When a soccer ball is hit, it goes at a very fast speed, velocity and gathers energy as it heads towards the goal post. When it finally hits the net, the net is pushed pretty far back until it stops the ball from its motion and reduces it velocity. This is what is supposed to happen when a bullet hits a body armor.
However, the bulletproof vest material cannot afford to push the bullet as far back as the goal post would. It ends up pushing it into the body of the wear at the point of interaction or impact. This leaves a blunt force trauma on the small concentrated area of impact, which can either cause mild injuries or serious internal injuries.
To reduce the concentration of the blunt trauma, body armor must be with bulletproof materials made out of tight weaves. Having individually twisted threads increases the density and thickness of each fiber. This would spread the impact of the hit around a particular area, instead of a select spot.
Bulletproof materials that are coated in resin-based substances and encased between plastic film layers can be used to achieve a more rigid effect upon impact. Sure, if you’re hit by a speeding bullet, you will feel the impact, regardless of whatever you are putting on. But if the impact of the bullet can be properly spread all over the vest rather than a defined area, the victim might not get seriously hurt.
Body armor is made up several layers which act like different “goal posts”, each slowing down the speed and impact of the bullet till it finally stops. However, no body armor is totally impenetrable. This is why the term “bulletproof” is more of an overstatement. “Bullet resistant” is a better word. Blunt force trauma can cause some serious damage if the material of a body armor is not up to standard. Ensure that you get the best bullet proof vest before going out in the face of danger.
