Abstract: A composite member comprises first and second elongate composite elements. Each has a wedge shaped end with a complimentary tapered end surface. At least one of the components is formed of a stack of fiber layers impregnated in resin, with the tapered end surface being formed by each fiber layer extending longitudinally progressively further than the adjacent layer towards the thin end of the wedge at which the fiber layers have the greatest longitudinal extent. The components are joined at their tapered ends by an adhesive, and the properties of the cured composite material of the at least one component and/or the properties of the adhesive are different in the vicinity of the thin end of the wedge as compared to the rest of the tapered surface in order to reduce the stress concentrations in this region.

Abstract: A wind turbine blade and a method of moulding a wind turbine blade tip section. The overall wind turbine blade has an elongate structure extending in a radial sense in a finished wind turbine. The blade comprises a fairing that one is supported along its length by a spar extended along the full length of the fairing from the root end to the tip. The fairing is in two parts with a main part extending from the root for most the of the longitudinal length of the blade and the tip section forming the remainder of the blade.

Abstract: A method of forming a structural connection between a spar cap 14 and an aerodynamic fairing 12. A composite comprising an uncured matrix and a compressible solid is applied between the spar cap and fairing and is then compressed and cured to adhere the fairing to the spar cap. The cured matrix composite has a void volume of at least 20%. The high void volume means that as the fairing is compressed into place and compresses the composite, it has space in which to deform so as not to place undue stress on the fairing and to produce a lightweight connection.

Abstract: A rotor blade assembly includes a rotor blade defining a pressure side and a suction side extending between a leading edge and a trailing edge. Further, the rotor blade assembly includes at least one structural feature secured within the rotor blade and spaced apart from the trailing edge to define a void between the pressure side, the suction side, and the trailing edge. Moreover, the rotor blade assembly includes an adhesive filling the void between the pressure side, the suction side, and the trailing edge to provide an adhesive connection between the pressure side, the suction side, the trailing edge, and the structural feature(s). In addition, the adhesive contacts the structural feature(s) at an interface and defines a fillet profile.
