History of fiberglass
Fiberglass is the original fiber reinforcement of modern composites. Though the ancient Phoenicians,
What is fiberglass made of?
Textile-grade glass fibers are made from silica (SiO2) sand, which melts at 1720°C/3128°F. SiO2 is also the basic element in quartz, a naturally occurring rock. Quartz, however, is crystalline
Sodium and Potassium Oxide
How to fiberglass form?
Although a viable commercial glass fiber can be made from silica alone, other ingredients are added to
From the batch house, another pneumatic conveyor sends the mixture to a high temperature (≈1400ºC/2552ºF) natural gas-fired furnace for melting. The furnace is typically divided into three sections, with channels
3. Fiber forming
Glass fiber formation, or fiberization, involves a combination of extrusion and attenuation. In extrusion, the
4. Sizing coating
In the final stage, a chemical coating, or sizing, is applied. (Although the terms binder, size and sizing often
Finally, the drawn, sized filaments are collected together into a bundle, forming a glass strand composed of 51 to 1,624 filaments. The strand is wound onto a drum into a forming package that resembles a spool of
