Armored Cars and Shatterproof Glass

Published by:

If you are in the front line of a danger zone, preventing bullets from every direction, you will require all the help that you can get. This is when armored cars prove to be helpful as they are made of bulletproof glass.  A bulletproof car can dissipate the energy of the bullet.

Reason Ordinary Glass Shatters

If you have ever played baseball or cricket, you will know that the trick to catch a fast-moving ball is to move your hand back and then gradually stop the ball. This way you reduce the energy slowly. This will reduce the force on your hand so that the catch hurts somewhat less. In scientific terms, the force which the ball exerts on the hand is pretty equal to the rate at which the momentum of the ball changes.  Thus, if you change the momentum gradually simply by bringing it a halt slowly, the force will feel somewhat reduced.  If you stop a ball almost instantly, you are going to feel a hefty smack on your hand.  However, if you take your hands four times longer for bringing the ball to rest, your hand is going to feel quarter force. Thus, the ball is going to hurt you much less.

Unlike your hand, a piece of glass will not be able to move.  If bullet is fired at an ordinary glass, the glass will not be able to bend to absorb the energy gradually.  Thus, it will just shatters and the bullet will carry on without the loss of momentum. It is completely ineffective is slowing it down.

How to Make Bulletproof Glass?

Traditional bulletproof glass used in the armored cars is made of alternate layers of glass and plastic.  Here, the plastic is thin film of PVB or polyvinyl butyric. New and strong bulletproof glass uses sandwich of plastic and glass which is made of acrylic glass, polycarbonate, ethylene vinyl acetate with the plastic layers and thick glass.

For making a simple PVB based shatterproof glass  for armored cars, the thin PVB film is known to be compressed in between the thicker glass for making a laminate that is compressed and heated to that the plastic melts and beings bonding with the glass.  This process usually happens in a vacuum for preventing the air from being trapped between the layers. The primary difficult with the process is to ensure that the glass and the plastic layers stick together properly without any air being trapped between them.

Where is the Bulletproof Glass Used?

Bulletproof glass comes in different shapes and sizes. It can be used for armored cars for protection. Thicker the glass and more layers it has, the more energy it can to absorb and more protection it will offer.

The only problem is the thicker the armored cars, the heavier it becomes.  This will make it slightly more opaque.

Standards for Bulletproof Glass

Different standards exist in various parts of the world.  Modern bulletproof glass is just a variation on the laminated safety glass. The primary idea is to use polyvinyl plastic in the laminated glass dates.

Check up on the Engine Oil

You can honestly opt to do it with on a regular basis or on a monthly basis. Make sure that the vehicle is parked on a ground level so that the dipstick reading is accurate.

Check the Tire Air Pressure

Use an tire pressure gauge atleast once a month to check the inflation pressure of each tire when it is cold and has not been driven for more than a couple of hours, also this includes the spare.

Wash the Vehicle

If possible, wash your Toronto car rental every week- wash the body, the fender Wells, undercarriage and such.

Replace the Drive Belts, Hoses and Timing belt

For the belts and hoses stick to doing it every couple of years. For the timing belt, stick to the interval recommended by the manufacturer- generally with every 60,000 to 80,000 miles.

Check up on the Air Filter

Remove the air filter and then hold it up to strong light. Now, if you can’t see light then replace it.

Check up on the Constant-Velocity-Joint Boots

Present on the front wheels, these rubber boots also known as CV boots are there on the drive axles. So if you find that they are cracked, cut or leaking then replace them.

Look at the Brakes

Check brakes atleast twice a year and if you can look after your own brake work then remove all the wheels and thoroughly examine the brake system. Make sure to replace worn lining, pads, rotors, drums and such.

Check up on the Fluids

If you have a Toronto car rental where the automatic transmission isn’t sealed then check for its dipstick by keeping the engine running. Also check on the power steering pump dipstick.

Inspect the Exhaust System

Go under the car and look for rusted exhaust parts which might need to be replaced. While under there tighten loose clamps as well.

Clean up the Radiator and check the battery

Remove debris and wash the outside of a radiator with a soft brush and detergent solution to prevent overheating. While at it, also inspect the battery’s terminals, fluid level as well as cables to ensure that no corrosion has taken place and that they are securely attached.

Drain and Flush the Cooling System and change the Automatic-Transmission Fluid

Now, the first part honestly is a hassel with the antifreeze so it is advisable to just let a shop do it. In regards to the Automatic-Transmission Fluid, check the owner’s manual to see when you need to replace the fuel.

No matter what replacement or changes you are doing alone, make sure to consult the owners manual at every step.
