Abstract[English]
A wind turbine blade (24) of a wind turbine (12) including a shell (36) having a sidewall (40). The sidewall (40) including an outer skin (50) of a first composite, an inner skin (52) of a second composite, a cellular structure (56) including a plurality of walls (70) defining a plurality of cells (76). The cellular structure (56), including an outer wall (90), an inner wall (80), and a mid portion (98), between the outer skin (50) and the inner skin (52). A first composite layer (96) including the outer wall (90) and a matrix (94) of the first composite. A second composite layer (86) including the inner wall (80) and a matrix (84) of the second composite. Cells (76) in the mid portion (98) of the cellular structure (56) are closed cells. A method for manufacturing a wind turbine blade (24) including admitting a resin (130) to impregnate into fiber layers (110, 114). The resin (130) penetrates the cellular structure (56) to form composite layers (86, 96).[French]
L'invention concerne une pale d'éolienne (24) d'une éolienne (12) comprenant une coque (36) présentant une paroi latérale (40). La paroi latérale (40) comprend une peau externe (50) d'un premier composite, une peau interne (52) d'un second composite, une structure alvéolaire (56) comprenant une pluralité de parois (70) définissant une pluralité de cellules (76). La structure alvéolaire (56), comprenant une paroi externe (90), une paroi interne (80) et une partie médiane (98) entre la peau externe (50) et la peau interne (52). Une première couche composite (96) comprend la paroi externe (90) et une matrice (94) du premier composite. Une seconde couche composite (86) comprend la paroi interne (80) et une matrice (84) du second composite. Des cellules (76) dans la partie médiane (98) de la structure cellulaire (56) sont des cellules fermées. L'invention concerne un procédé de fabrication d'une pale d'éolienne (24) comprenant l'admission d'une résine (130) à imprégner dans des couches de fibres (110, 114). La résine (130) pénètre dans la structure cellulaire (56) pour former des couches composites (86, 96).
