Abstract[English]
According to a first aspect of the present invention there is provided a wind turbine blade comprising an elongate reinforcing structure. The reinforcing structure comprises a plurality of strips of fibre-reinforced polymer arranged in a stack, and an interface layer arranged between two adjacent strips in the stack. The interface layer comprises a fabric with primary fibres and secondary fibres. The primary fibres are mutually-aligned within the plane of the interface layer, and the secondary fibres are interspersed with the primary fibres. The secondary fibres are shorter than the primary fibres.[French]
Un premier aspect de la présente invention concerne une pale d'éolienne comprenant une structure de renforcement allongée. La structure de renforcement comprend une pluralité de bandes de polymère renforcé par des fibres agencées dans un empilement et une couche d'interface agencée entre deux bandes adjacentes dans l'empilement. La couche d'interface comprend un tissu avec des fibres primaires et des fibres secondaires. Les fibres primaires sont mutuellement alignées dans le plan de la couche d'interface et les fibres secondaires sont intercalées avec les fibres primaires. Les fibres secondaires sont plus courtes que les fibres primaires. [Figure 3 pour accompagner l'abrégé]
