Glass Fiber | Physical And Chemical Properties Of Glass Fiber

Glass fiber is a hard fiber. Its tenacity is so high. It is in second position regarding on tenacity. After cabler aramid, glass fiber is stand on. The production of glass fiber is not so easy. The chemical composition of glass fiber is important to decide because it depends on the final product properties.

Here, I have presented a list of physical and chemical properties of glass fiber. I think this will help you to identify glass fiber from other fibers.

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

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.
    8. Effect of sun light: Sun light does not change the glass fiber properties.

That’s all about glass fiber properties.

Chemical Composition of Glass Fiber Production

Glass fiber is special types of synthetic fiber. It is a very strong fiber. Its tenacity is higher than other fibers. It is heavy in weight. It is generally used in special purpose. Special types of fabric are made by this glass fiber. It is generally use to make flame proof, water proof fabrics or to make the body of sports car and parts of crafts.

Chemical Composition of Glass Fiber: Glass fiber is made by the combination of following chemicals. But this composition could be changed depending on the requirements of the user. The chemical composition of glass fiber is given below.

           Silicon Dioxide : 55%

                   Calcium Oxide : 16 – 25%

                 Aluminium Oxide : 12 – 16%

                      Baron Oxide : 8 – 13%

Sodium and Potassium Oxide: 0 – 1%

               Magnesium Oxide : 0 – 6%

This composition is calculated based on 100%. By blending and mixing all of the above chemicals glass fiber is formed.

Although, glass fiber is not a popular fiber but we should be aware about the glass fiber.
