The glass fiber rod is a composite material in which glass fiber and its products (glass cloth, tape, felt, yarn, etc.) are used as reinforcing materials and synthetic resin is used as a base material. The concept of composite material refers to a material that cannot meet the requirements of use. It needs to be composed of two or more materials to form another material that can meet people’s requirements, namely composite materials. A single kind of glass fiber, although high in strength, but loose between fibers, can only withstand tensile forces, can not withstand bending, shearing and compressive stress, but also difficult to make a fixed geometry, is a soft body. If they are bonded together with synthetic resin, they can be made into a variety of rigid products with a fixed shape, can withstand tensile stress, glass fiber rods are mainly used for sunshade support rods, awning struts, tent poles, agricultural greenhouses Struts, mosquito net struts, luggage skeleton, nursery stents and so on.
