Overview
This lecture explains how bulletproof glass works, focusing on its structure and materials used to provide protection against bullets.
Structure of Bulletproof Glass
- Bulletproof glass is made from multiple layers of glass and plastic.
- Layers of tough plastic (often polycarbonate) are sandwiched between layers of glass.
- The combination of materials absorbs and disperses the energy of a bullet.
- The thickness and number of layers determine the level of protection.
How Bulletproof Glass Works
- When a bullet hits the glass, initial glass layers break to absorb some energy.
- Plastic layers slow down and trap the bullet by flexing without shattering.
- The overall construction prevents the bullet from penetrating through the glass.
- More layers and thicker materials increase protection but add weight and thickness.
Key Terms & Definitions
- Bulletproof Glass — A transparent material designed to resist penetration by bullets, made from multiple layers of glass and plastic.
- Polycarbonate — A tough, transparent plastic often used in bulletproof glass for its impact-resistant properties.
- Laminated Glass — Glass bonded with plastic layers to enhance strength and prevent shattering.
