Abstract: A reinforcing structure for a wind turbine blade is in the form of an elongate stack of layers of pultruded fibrous composite strips supported within a U-shaped channel. The length of each layer is slightly different to create a taper at the ends of the stack; the centre of the stack has five layers, and each end has a single layer. The ends of each layer are chamfered, and the stack is coated with a thin flexible pultruded fibrous composite strip extending the full length of the stack. The reinforcing structure extends along a curved path within the outer shell of the blade. The regions of the outer shell of the blade on either side of the reinforcing structure are filled with structural foam, and the reinforcing structure and the foam are both sandwiched between an inner skin and an outer skin.

Abstract: A reinforcing structure 9 for a wind turbine blade is in the form of an elongate stack 27 of layers 31 of pultruded fibrous composite strips supported within a U-shaped channel 28. The length of each layer 31 is slightly different to create a taper at the ends of the stack; the centre of the stack 27 has five layers 31, and each end has a single layer 31. The ends of each layer 31 are chamfered, and the stack is coated with a thin flexible pultruded fibrous composite strip 33 extending the full length of the stack 27. The reinforcing structure 9 extends along a curved path within the outer shell of the blade. During configuration of the blade components within a mould 37, the reinforcing structure 9 is introduced into the mould 37 by sliding the channel 28 along the surface of an elongate wedge 29 within the mould 37 along the curved path. The wedge 29 is oriented along its length at an angle depending on the curvature of the path at that position so as to guide the reinforcing structure 9 into the desired position. The regions of the outer shell of the blade on either side of the reinforcing structure 9 are filled with structural foam 17, and the reinforcing structure 9 and the foam 17 are both sandwiched between an inner skin 18 and an outer skin 19.
