NOVELTY - Special-shaped glass fiber comprises silicon oxide (SiO2), aluminum oxide (Al2O3), magnesium oxide (MgO), copper oxide (CuO), calcium oxide (CaO), barium oxide (BaO), zinc oxide (ZnO), nickel oxide (NiO), silicon oxide (SiC) and graphene oxide. The profile ratio of the profiled glass fiber is 3.6-4.2, the filling rate of the profiled glass fiber is 85-90%, and the elongated ratio of the profiled glass fiber is 1.2-5. USE - Special-shaped glass fiber. ADVANTAGE - The special-shaped glass fiber has higher tensile strength and tensile modulus by controlling the formulation components and the content of each component, and at the same time, the product has a higher filling rate and a stable profiled ratio, and experimental results show that the longitudinal tensile strength of the profiled glass fiber can reach 6000 megapascal or more, the transverse tensile strength can reach 5200 megapascal or more, and the tensile modulus can reach 121 gigapascal or more. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing a shaped glass fiber, which involves weighing the components included in the profiled glass fiber in proportion, mixing uniformly, heating and melting, clarifying, and obtaining a high-temperature glass liquid, and high-temperature glass liquid flows out through the leak hole, is drawing, and is sequentially cooling and infiltrating to obtain a shaped glass fiber.
