Abstract (en)
[origin: WO2020043469A1] The invention relates to a fiber-reinforced composite blank (210) for a fiber-reinforced composite component, in particular for a fiber-reinforced composite component of a wind turbine, comprising a layered construction with a form core (220), consisting of or comprising a form core material, and a fiber layer (230a, b) bordering on the form core (220), said fiber layer consisting of or comprising a fiber layer material, and multiple reinforcing rods (240) introduced into the form core (220) and consisting of or comprising a reinforcing material, wherein the reinforcing material has higher stiffness than the form core material. The multiple reinforcing rods (240) are in this context introduced into the form core (220) at an angle to a form core plane. Furthermore, at least one reinforcing rod of the multiple reinforcing rods (240) is introduced into the form core (220) at an angle to a direction normal to the form core plane.
