What is fiberglass?

Answer 1

Fiberglass is a composite material reinforcement. Parts made using fiberglass are typically still referred to as "fiberglass."

Fiberglass parts are made from strands of glass fiber which are suspended in a polymer (plastic) matrix (resin). Fiberglass cloth is a fabric comprised of strands of glass fibers that are bundled together in different weaves.

Unlike carbon fiber, fiberglass can be purchased in the form of cloth where long continuous stands of glass are woven into a fabric using a predetermined weave, or in chopped strand mat where short strands of glass are formed randomly into a fabric and held together by a weak styrene styrene bonding agent. Fiberglass cloth has good direction strength while fibergas mat has a lower strenght but is equal in all directions. The two most common glass types are E-glass and S-glass. S-glass is a higher strength glass reinforcement, sometimes referred to as structural-glass, and as you can imagine it is a bit more expensive.
