Are fiber glass lightweight composites?
Glass fiber itself is an inorganic non-metallic material, glass fiber as the base material of composite materials, and resin with the formation of composite materials, alone, glass fiber is a composite material unscientific.
Belong to. This definition is not clear, but you want to, ah, metal matrix composite material, there are still light, that can not count ~!"Glass fiber reinforced plastics appeared in the 1940s, not only light, high strength, but also better insulation"
You confused, glass fiber is a kind of fiber, is often used as a composite material inside a reinforced material. (other fibers can also, such as carbon fiber, aramid fiber, DuPont brand called Kevlar, Kevlar basalt fiber etc.). Lightweight composite is a general term for a class of low density composites. This classification is not rigorous in composites, and is generally made of sandwich materials or lightweight fillers.
