Abstract[English]
A shear web (44) for a wind turbine blade (20) includes a lower flange (46), an upper flange (48) and a web structure (50) extending between the lower and upper flanges 5 (46, 48), wherein at least one of the lower flange (46), upper flange (48), and the web structure (50) includes an open lattice structure (60, 62, 71, 94, 100) having a plurality of elongate fibrous composite spindles (64, 66, 68, 70, 72, 74, 96, 98) intersecting each other at multiple nodes of the structure. A method of making the shear web (44) using a continuous fiber-reinforced additive manufacturing method is also disclosed.[French]
Une âme de cisaillement (44) pour une pale d'éolienne (20) comprend une bride inférieure (46), une bride supérieure (48) et une structure d'âme (50) s'étendant entre les brides inférieure et supérieure (46, 48), au moins l'une de la bride inférieure (46), de la bride supérieure (48), et de la structure d'âme (50) comprenant une structure en treillis ouvert (60, 62,71, 94, 100) ayant une pluralité de broches composites fibreuses allongées (64, 66, 68, 70, 72, 74, 96, 98) se croisant au niveau de multiples nœuds de la structure. L'invention concerne également un procédé de fabrication de l'âme de cisaillement (44) à l'aide d'un procédé de fabrication additive continue à renforcement par fibres.
