Title
(EN) MANUFACTURE OF A REINFORCED SHELL PART OF A WIND TURBINE BLADE
(FR) FABRICATION D’UNE PARTIE D'ENVELOPPE RENFORCÉE D’UNE PALE D’ÉOLIENNE
Abstract
(EN)
Disclosed is a method for manufacturing a reinforced shell part for a wind turbine blade (10) comprising, providing a shell having an (39a), optionally arranging a plurality of fibre layers on the inner surface (39a) of the shell to form a base part of a reinforced section, providing a preform of a first inlay, arranging the preform of the first inlay on the inner surface of the shell and/or on the base part of the reinforced section, providing a preform of a second inlay, arranging the preform of the second inlay on the inner surface of the first shell part and/ or on the base part of the reinforced section, arranging at least one pultrusion layer on the preform of the first inlay, the preform of the second inlay, and the inner surface of the shell and/or the base part of the reinforced section, wherein the pultrusion layer comprises a plurality of pultruded members grouped together, the pultrusion layer having a proximal edge, a distal edge and two opposing lateral edges, and wherein the pultrusion layer is arranged in a spanwise direction of the blade such that the proximal edge of the pultrusion layer is arranged on the preform of the first inlay and the distal edge of the pultrusion layer is arranged on the preform of the second inlay.
(FR)
La présente invention concerne un procédé de fabrication d’une partie d'enveloppe renforcée pour une pale d’éolienne (10) qui comprend l'utilisation d’une enveloppe ayant une surface interne (39a), la configuration éventuelle d’une pluralité de couches de fibres sur la surface interne (39a) de l’enveloppe pour former une partie de base d’une section renforcée, l'utilisation d’une préforme d’une première incrustation, l'agencement de la préforme de la première incrustation sur la surface interne de l’enveloppe et/ou sur la partie de base de la section renforcée, fournissant une préforme d’une seconde incrustation, l'agencement de la préforme de la seconde incrustation sur la surface interne de la première partie d’enveloppe et/ou sur la partie de base de la section renforcée, l'agencement d’au moins une couche de pultrusion sur la préforme de la première incrustation, la préforme de la seconde incrustation et la surface interne de l’enveloppe et/ou la partie de base de la section renforcée, la couche de pultrusion comprenant une pluralité d’éléments pultrudés regroupés ensemble, la couche de pultrusion ayant un bord proximal, un bord distal et deux bords latéraux opposés, et la couche de pultrusion étant disposée dans le sens de l'envergure de la pale de sorte que le bord proximal de la couche de pultrusion est disposé sur la préforme de la première incrustation et le bord distal de la couche de pultrusion est disposé sur la préforme de la seconde incrustation.
