Fiberglass is a synthetic glass based composite material composed of glass fibers which create strength and a matrix that binds the fibers together. Other substances such as fillers are used to reduce the cost and improve process ability and dimensional stability. Fiberglass was first used for home furnace filters and insulation.
Fiberglass has several unique properties. It has a high strength to weight ratio, is impact and fatique resistant and has low thermal and electrical conductivity.
Fiberglass is often used in: sporting equipment, surfboards, appliances, aircraft panels, automobiles, thermal insulation, electrical insulation, sound absorption panels, bows, crossbows, boat hulls, etc.
