Patent

CA 2479604

The invention relates to a wind turbine blade and a transitional shell blank for the manufacture of the shell of a wind turbine blade, the blade or the transitional shell blank being made of fibre-reinforced polymer including a first type of fibres (1, 3, 6) of a first stiffness and a first elongation at breakage, and a second type of fibres (2, 5, 7) of a different stiffness and a different elongation at breakage. According to the invention the two types of fibres are distributed in the polymer matrix. When seen in a sectional view perpendicular to longitudinal direction of the blade or the transitional shell blank, the quantitative ratio of the two types of fibres varies continuously in the longitudinal direction of the blade or of the transition shell blank.

L'invention concerne une pale d'éolienne et une ébauche de coque transitionnelle destinée à la fabrication de la coque d'une pale d'éolienne. Ladite pale ou ébauche de coque transitionnelle est formée d'un polymère à fibres renforcées comprenant un premier type de fibres (1, 3, 6) d'une première raideur et d'une première élongation à la rupture et un second type de fibres (2, 5, 7) d'une raideur et d'une élongation à la rupture différentes. Selon l'invention, les deux types de fibres sont réparties dans une matrice polymère. Lorsqu'on l'observe en coupe transversale perpendiculaire au sens longitudinal de la pale ou de l'ébauche de coque transitionnelle, le rapport quantitatif entre les deux types de fibres varie de manière continue dans le sens longitudinal de la pale ou de l'ébauche de coque transitionnelle.
