Title (EN) METHOD OF MANUFACTURING A WIND TURBINE ROTOR BLADE
(FR) MÉTHODE DE FABRICATION D'UNE PÂLE DE ROTOR D'ÉOLIENNE
Abstract:
(EN) 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.
(FR) La présente invention concerne une méthode de fabrication d'une pâle de rotor d'éolienne, une pâle de rotor d'éolienne pouvant être obtenue par ladite méthode, un procédé de pultrusion pour produire une préforme allongée (97) destinée à être intégrée dans une pâle de rotor d'éolienne et une préforme allongée (97) pouvant être obtenue par ledit procédé. Le procédé de fabrication de pâle implique un procédé de pultrusion pour obtenir la préforme (97), l'incorporation de la préforme (97) dans une ou plusieurs parties de la pâle, l'infusion d'une résine dans ladite ou lesdites parties de pâle contenant la préforme (97), et l'assemblage de la pâle de rotor comprenant ladite ou lesdites parties de pâle.
