  • Main beam for wind turbine blade and manufacturing method thereof
    Patent number: 11905921
    Abstract: A main beam for wind turbine blade, comprising: one or more carbon fiber pultruded bodies, wherein, each carbon fiber pultruded body comprising one or more carbon fiber pultruded sheets, the carbon fiber pultruded sheets are stacked along the thickness direction and are formed by curing a first infusion material, wherein a glass fiber infusion material is arranged between every two carbon fiber pultruded sheets; one or more inlays, which are arranged adjacent to the carbon fiber pultruded body in a direction perpendicular to the thickness direction of the main beam; one or more overlays, which cover the carbon fiber pultruded bodies and/or the inlays on both sides in the thickness direction of the main beam; and a second infusion material, which impregnates carbon fiber pultruded bodies, the inlays and the overlays.
