Abstract

Method for manufacturing a preform element, method for manufacturing a rotor blade, preform element, rotor blade, wind turbine and mold Method for manufacturing a preform element (23) used in particular for manufacturing a rotor blade (4) of a wind turbine (1), comprising the steps of: Providing a mold (7) with a molding surface (8), one or more preform building components (9), an adhesive agent, and a penetration arrangement (13) comprising a plurality of elongated penetration elements (15) protruding from a base structure (14) and/or from the molding surface (8), wherein at least one of the preform building components (9) is a textile component (10) comprising a plurality of fibers, Arranging the preform building components (9) and the adhesive agent on the molding surface (8), wherein the textile component (10) and the adhesive agent are arranged at least sectionally in contact with each other, wherein the textile component (10) and/or the penetration arrangement (13) are arranged in such manner that the penetration elements (15) protrude into the textile component (10) locally spacing the fibers, Activating the adhesive agent for at least partly soften and/or liquefying the adhesive agent, Solidifying the activated adhesive agent, and Separating the penetration arrangement (13) and the preform components (9) for forming the preform element (23) comprising channels (24) protruding from an outer surface (25) of the preform element (23) into the textile component (10) at the positions of the penetration elements (15).
