Claim 9:
10. A method for manufacturing the main beam for wind turbine blade, comprising the following steps:
providing one or more carbon fiber pultruded bodies, each of the one or more carbon fiber pultruded bodies comprising one or more carbon fiber pultruded sheets, the one or more carbon fiber pultruded sheets are stacked along a thickness direction of the one or more carbon fiber pultruded bodies, wherein the one or more carbon fiber pultruded sheets are formed by curing a first infusion material, wherein the one or more carbon fiber pultruded sheets comprise a plurality of carbon fiber pultruded sheets, and a glass fiber infusion material is arranged between every two of the plurality of carbon fiber pultruded sheets;
arranging one or more inlays adjacent to the one or more carbon fiber pultruded bodies in a direction perpendicular to a thickness direction of the main beam;
arranging one or more overlays on the one or more carbon fiber pultruded bodies and/or the one or more inlays on both sides in the thickness direction of the main beam; and
impregnating the one or more carbon fiber pultruded bodies, the one or more inlays and the one or more overlays with a second infusion material.
