Abstract[English]
Aspects of the present disclosure relates to a wind turbine blade. The blade comprises a main reinforcement structure, the main reinforcement structure comprising a main windward reinforcement structure and a main leeward reinforcement structure; a rear reinforcement structure, the rear reinforcement structure comprising a rear windward reinforcement structure and a rear leeward reinforcement structure; and a trailing edge reinforcement structure arranged between the rear reinforcement structure and a trailing edge of the blade. The main windward reinforcement structure and the main leeward reinforcement structure comprise layers of pultruded fibres of a first material. The rear windward reinforcement structure and/or the rear leeward reinforcement structure comprise layers of pultruded fibres of a second material, the pultruded fibres of the first material having a Young's modulus greater than the pultruded fibres of the second material. The trailing edge reinforcement structure comprises fibres aligned with the trailing edge of the blade.[French]
Des aspects de la présente invention concernent une pale d'éolienne. La pale comprend une structure de renforcement principale. Ladite structure de renforcement principale comprend une structure de renforcement au vent principale et une structure de renforcement sous le vent principale ; une structure de renforcement arrière présentant une structure de renforcement arrière au vent et une structure de renforcement arrière sous le vent ; et une structure de renforcement de bord de fuite disposée entre la structure de renforcement arrière et un bord de fuite de la pale. La structure de renforcement au vent principale et la structure de renforcement sous le vent principale comprennent des couches de fibres pultrudées d'un premier matériau. La structure de renforcement arrière au vent et/ou la structure de renforcement arrière sous le vent comprennent des couches de fibres pultrudées d'un second matériau, les fibres pultrudées du premier matériau ayant un module de Young supérieur aux fibres pultrudées du second matériau. La structure de renforcement de bord de fuite comprend des fibres alignées avec le bord de fuite de la pale.
