The emergence of high-strength and high-modulus E8 fabric will bring great value to the wind energy market by further promoting the technological reformation and design innovation of large MW wind turbine blades. With lighter weight and higher strength and modulus，E8 fiberglass endows the blades with longer length, less blade deformation, better fatigue resistance and wider wind area adaptability, thus not only lowering the LCOE, but also further improving the wind area adaptability and service life of blades, which contributes to laying a solid foundation for the sustainable development of wind blades.
