This document provides information about glass fiber, including its composition, types, chemical and physical properties, uses, and structure. There are two main types of glass fiber produced commercially, known as E glass and C glass. Glass fiber is made of extremely fine fibers of glass and consists of sodium, calcium, and silicate substances. It has good tensile strength and resilience but poor elasticity and ability to resist friction. Its key uses include in aircraft/aerospace, appliances, construction, consumer goods, and more.

2. What is Glass fiber?
• Glass fiber is a material consisting of
numerous extremely fine fibers of glass.
• Glass Fibers spun for sodium , calcium ,silicate
and related substances forming the material
known as glass fiber.it is very complex
material but todays technology it is made
easily .

3. Types of glass fiber
• There are two main types of glass fiber in
large scale commercial production they are
• 1.E glass
• 2.C glass

4. Chemical properties of Glass fiber
• The chemical properties of glass fiber are given below.
1. Acids: Hydro choric acid and hot phosphoric acid causes harm to the
glass fiber.
2. Basic: It has enough protection ability to alkali.
3. Effect of bleaching: Bleaching agent does not cause harm to glass
fiber.
4. Organic solvent: It does not change on organic solvents.
5. Protection ability against mildew: It does not affected by mildew.
6. Protection ability against insects: Insect does not affect on glass fiber.
7. Dyes: It is not possible to dye after production. But it could be color
before production by adding dye in the solution bath.

5. Physical properties of Glass fiber
• The physical properties of glass fiber are given below.
1. Tenacity: 6.3 – 6.9 gm/den
2. Density: 2.5 gm/c.c
3. Elongation at break: 3%
4. Elasticity: Bad
5. Moisture Regain (MR%): 0%
6. Resiliency: Excellent
7. Ability to protest friction: Not good
8. Color: White or color less
9. Ability to protest friction: It can protect up to 3150C temperature. It loses energy
after passing 3150C
10. Lusture: Bright to light
