The strength of carbon fiber is higher than that of glass fiber. Carbon fiber is conductive, while glass fiber reinforced plastic is not.
It need for high strength, but also, and carbon fiber is only a single material, carbon fiber is conductive. In general, carbon fiber can be a raw material for glass fiber reinforced plastic. But the glass fiber reinforced plastic has now evolved into a general term. Not only the composite material made of resin and glass fiber is called glass fiber reinforced plastic. But the strength of the carbon fiber is much stronger than the glass fiber. Carbon fiber made for the composite material are often called glass fiber reinforced plastics.carbon fiber glass reinforced plastics used in anti-static condition are obviously different composite materials made of resin and glass fiber.
