Abstract
The present invention relates to a method of manufacturing a wind turbine rotor blade, to a wind turbine rotor blade obtainable by said method, to a pultrusion process for producing an elongated preform (97) for embedment in a wind turbine rotor blade and to an elongated preform (97) obtainable by said process. The blade manufacturing process involves a pultrusion process to obtain the preform (97), embedding the preform (97) within one or more parts of the blade, infusing a resin into said one or more blade parts containing the preform (97), and assembling the rotor blade including said one or more blade parts.
