Bullet proof vests are very important for police and military men and women. It helps keep them safe! Hi, Two kids from room 13! Bullet proof vests have lots of tightly-packed, woven fibers that catch the bullet and stop it from moving any further -- kind of how a soccer goal net catches the ball and keeps it from going any further.
The vests keep you safe from low-caliber handguns but are not strong enough to protect against higher-caliber weapons like rifles. We're so glad you asked these questions, Wonder Friends! You're right, Jason! Just because you wear a bulletproof vest doesn't mean that you will not get hurt.

Hi Jasmine and Amelia, today's Wonder is all about protection! When folks who keep us safe have to protect themselves from bullets, they wear bulletproof vests to prevent injury. Whilst searching for a new plastic to make lighter, stronger car tires, Stephanie Kwolek discovered the molecule Poly Paraphenylene Terephthalmide.
It is a polymer with an exciting secret…the molecules can be laid out in chains, side-by-side to create a hugely strong mesh that can also be spun into fabric!
And, added bonus, it can resist high heat and flames of up to around degrees! 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.
Note that the higher the protection level, the heavier the armor plate usually becomes. Some people may opt for as low as NIJ level II 2 protection if they only expect handgun rounds and knives as a threat. Keep in mind the caliber or the weapon you might face though. While NIJ level II 2 may do fine against a 9mm handgun, it is much less effective against higher caliber ones such as a.
Also, keep in mind that not all bullet proof vests or kevlar vest are stab proof or spike proof. Most body armor manufacturers include additional armor plate pockets so that the wearer can add hard body armor plates up to a level IV to his bullet proof vest to increase the ballistic protection level as well as stab proof capabilities similar to how plate carriers function.
Bullet proof vests are most often associated with Kevlar, and a Kevlar vest is one of the more popular types you can find. Nowadays you can find bullet proof vests made from a variety of materials. From kevlar vests, to ceramic body armor, and hard steel armor, there are many different choices to fit your threat level requirements. For people working as security guards or law enforcement officers — covert vests made of this material give an excellent level of protection.
It is also used in the manufacturing of overt vests, which are worn by military operatives with additional panels and plates for more protection from heavy enemy fire.
For example, a security guard will likely not require the same protection as a military operative in a war zone. Specially designed carriers for storage are an option if you want to be sure that your vest does not get creased or bent as this can compromise its integrity.
Hanging the vest is not recommended as it puts strain on the fibers.
