Definition: Fiberglass is the most common structural reinforcement used in composites. Raw silica (sand) is melted down in a giant furnace and extruded into tiny threads known as filaments. Thousands of these filaments are then combined into a woven or stitched cloth.
A fiberglass cloth, when impregnated with a liquid polymer resin, creates an extremely strong and lightweight composite. A fiberglass composite product is resistant to corrosion, non-conductive, and long lasting.
Alternate Spellings: Fibreglass
