摘要： A method of making a wind turbine blade in a blade mould is described. The wind turbine blade comprises a plurality of elongate reinforcing structures each comprising a stack of strips of fibre-reinforced polymeric material, and the method comprises: stacking strips of fibre-reinforced polymeric material to form a plurality of stacks (40), each defining a longitudinal axis; aligning the stacks relative to one another in an alignment zone outside the blade mould; supporting the stacks to maintain their relative alignment; transferring the plurality of stacks into the blade mould simultaneously while maintaining the relative alignment of stacks as the stacks are transferred; and integrating the stacks with other blade materials forming the blade in the blade mould. An apparatus for use in the method is also described.

摘要： A method of making an elongate reinforcing structure, such as a shear web, for a wind turbine blade is described. The reinforcing structure comprises a longitudinally-extending web and a longitudinally-extending flange. The flange extends along a longitudinal edge of the web and is arranged transversely to the web. The method involves providing a flange structure comprising a flange portion, and a projecting portion that extends along the length of the flange portion and projects transversely from a surface of the flange portion. The projecting portion is bonded between laminate layers of the web. The flange structure is preferably a pultruded component having a T-shaped cross-section. The method allows a simple, inexpensive and reconfigurable mould tool to be used. In preferred embodiments the mould tool has a flat surface without sidewalls.

摘要： Improvements relating to wind turbine blade manufacture 5 A method of making a wind turbine blade is described. The method involves providing a blade shell having an inner surface defining a mounting region and positioning a web in the mounting region. One or more web restraining devices are used to secure the position of the web in the mounting region. Each restraining device has a first portion attached to the web and a second portion attached to the inner surface of the blade shell. The 10 restraining devices are configured to prevent movement of the web in a first plane substantially parallel to the mounting region and to permit movement of the web in a second plane substantially perpendicular to the mounting region. The method further comprises moving the web in the second plane away from the mounting region and performing one or more preparatory operations on the mounting region with the web 15 moved away from the mounting region. The web is then repositioned in the mounting region by moving the web in the second plane back towards the mounting region.

摘要： The invention relates to a structural mat for reinforcing a wind turbine blade structure. The structural mat comprises two or more groups of bonded fibres, the fibres being bonded by a matrix substantially preventing relative movement of said fibres and wherein said groups are connected to each other by connection means limiting the relative movement of said groups. The invention further relates to a wind turbine blade and a method for manufacturing a wind turbine blade.

摘要： A production system for a wind turbine component is described. The system includes an elongate mould assembly extending in a longitudinal direction, the mould assembly comprising a mould surface and having a width that varies in the longitudinal direction. First and second tracks are defined respectively on opposite longitudinal sides of the mould surface. The perpendicular distance between the respective tracks varies along the length of the track. A transport assembly is moveable relative the mould assembly in the longitudinal direction. The transport assembly includes a pair of side supports arranged to move along the respective tracks, and a gantry supported above the mould assembly by the side supports. The gantry extends transverse to the longitudinal direction. The transport assembly is configured such that the side supports move relative to one another in a direction transverse to the longitudinal direction in accordance with the varying distance between the tracks as the transport assembly moves in the longitudinal direction.

摘要： A method and apparatus (14) for assembling a reinforcement web (12) for use with a wind turbine blade (10) are provided. A pre-formed flange structure (20) to be integrated with laminate layers (58, 60) to form the reinforcement web (12) is clamped into position against a mould end surface (76) using one or more locating clamps (16). The locating clamps (16) include first and second clamp blocks (80, 82) that are shaped to provide an external profile that avoids resin collection and bridging during resin injection molding, while allowing for clamping to be applied to the flange structure (20) with an easily assembled and disassembled removable engagement of the clamp blocks (80, 82). The locating clamp (16) prevents undesirable dislodgment of the flange structure (20) during the assembly process for the reinforcement web (12), and without necessitating the use of complex or expensive molding equipment or processes.

摘要： A wind turbine blade and associated method of manufacture is described. The blade comprises an outer shell formed of first and second half shells joined together. A shear web is arranged inside the outer shell. The shear web has a web panel disposed between first and second longitudinally-extending mounting flanges. The shear web is bonded to inner surfaces of the respective half shells via a first adhesive bond line between the first mounting flange and the inner surface of the first half shell and a second adhesive bond line between the second mounting flange and the inner surface of the second half shell. One or more bond spacers are provided in the second bond line, and optionally in the first bond line. The bond spacers are compressed between a shear web mounting flange and an inner surface of a half shell and are plastically deformed. The method of making the shear web involves compressing and the one or bond spacers in the bond line(s) such that they undergo plastic deformation. This results in high quality bond lines.

摘要： A method of making a wind turbine blade is described. The wind turbine blade comprises first and second half shells joined together and a shear web bonded between inner surfaces of the respective half shells. The blade is made in a one-stage join up process, which involves supporting the half shells in respective mould halves, and arranging one of the half shells on top of the other half shell with the shear web arranged between the two half shells. Adhesive is provided between the shear web and the inner surfaces of the respective half shells. During the join-up process, the shear web is supported by stabilisers. The use of stabilisers avoids the need for a jig to support the shear web. Stabilisers attached to an inboard end of the shear web may remain accessible after the join-up and can be removed.
