After conducting research and experimentation, I have decided to put out some information that I have learned about DIY Homemade Body Armor and material penetration capability of bullets in general.  I put together a video about the topic.  As a disclaimer do not use this as a substitute for body armor.
Please share with me and others your ideas for homemade body armor or what factors contribute to a bullets ability to penetrate.
Homemade Body Armor and Bullet Penetration Basics
1.Ceramic Front Plate: The ceramic plate has a relatively high compressive and shear strength and that act to absorb the energy of the bullet and degrade its material and shape.  Ceramic tiles are available in different ratings. The ceramic tile strips away the copper jacket and exposes the softer lead core.  
2.Fabric Back Plate:  The layered fabric plate is comprised of any fabric that has a tight weave and is strong under tension.  The fabric back plate exhibits a high tensile strength as well as a minimal amount of shear strength.  Fabrics such as denim, canvas, nylon, Kevlar, or fiberglass can all be used for this purpose and should be comprised of 8 layers at minimum.  
3.Adhesive: Adhesives when applied and impregnated into the fabric layers increases the tensile and shear strength as well as provides compressive strength to the composite material.  Use polyurethane base like Locktite Premium Proline adhesive.

telephone books - from experience they work great.

Not a body armor forum.

Why are you reposting this?

It was tested by MythBusters and it really worked.
A car covered in telephone book...poorman's armored car.

I do not understand the obsession with homemade body armor, when there are multiple sources from which to purchase actual body armor, that has been designed, manufactured, and tested by professionals.

Didnt you get pee pee slapped already for pimping your channel?

Didn't old time gun slingers wear silk embroidered vest to act as armored vest?
