Most people think that glass is a fragile and hard object and is not suitable as a structural material. But if it is drawn into filaments, its strength will be greatly increased and it has flexibility, so it can become an excellent structural material after changing its shape with resin. As its diameter becomes smaller, the strength of the glass fiber increases. These characteristics make the use of glass fiber far more extensive than other types of fiber.
