When you see the glass counter of lead might think at first glance it is exactly the same as ordinary glass, but once you start shooting you will know that there is a big difference.
Once ordinary glass collisions strongly anything Sathishm and scattered it hundreds of small pieces, but this is not the case with bullet resistant glass and designed to withstand several shots of the lead, depending on the thickness and type of weapon that is shooting it.

You may have ever wondered what makes this glass different from ordinary glass despite strong congruence between them and allows him impulsive repelled several bullets at him at speeds of up to 1220 kilometers per hour?

This will answer what it is today in the first article of the articles series "how it works" , which you will learn where the modus operandi of a lot of things around us suspiciously simple and easy.  

At the outset let us ask whether the glass material injury or a liquid? In fact the glass a special type of solids called  Amorphous solid  or non-solid materials amorphous in this material are atoms fixed and molecules is moving but do not constitute crystals but randomly distributed and thus Glass, fixed mechanically like solids but has distributed non-structured molecules such as liquids, consisting of these When the material melt solid at temperatures too high and then cooled rapidly which is what happens when the glass manufacturing.

Every product from glass producers resistant to lead his own excellence to his ways, but all of them follow the approach and one which add a layer of polypropylene carbonate - Polycarbonate between two layers of ordinary glass in a process called Lamination or "lamination or packaging" result in material thick glass-like, substance polycarbonate plastic material is "of a thermo-plastic polymers" transparent powerful known by other names such as Lexan or Makroclear .      

Bullet-proof glass usually have a thickness between 7 and 75 millimeters, at the launch of the bullet on this glass will penetrate bullet outer layer of glass, but the second layer of polypropylene carbonate will absorb the energy the bullet and stop it before it reaches the last layer of glass. As mentioned the thickness of the glass is what will determine its ability to repel bullets stronger, Valrsasp being launched from a rifle or sniper Srahta capacity and much greater than those that have been launched from an ordinary pistol.

There are also bulletproof glass from one direction to allow those who are shooting him to defend himself, and made by replacing the carbonate polyurethane layer that we have mentioned two layers, one flexible and other fragile.

When firing a shot at this type of glass from the outside Vstakhtriq bullet fragile class in the beginning and then Sttnather parts around the collision point (parts Stteixr Neat, but will not fall because it is coherent by the class that followed exactly looking glass car front) to absorb part of the energy bullet across a large area and then comes the role of the elastic layer to absorb the remaining part of the energy and stop bullets.

Now imagine when the bullet is launched from inside the bullet would run into in the beginning with the flexible portion and thus the power of the bullet will be concentrated on a small area will cause a bend in this class and then be destroyed as a result of the fragile layer that automatically pressure towards the outside and then the bullet will pierce the elastic layer.
