Abstract: A system and method for the manufacture of a wind turbine blade component is described, preferably a shear web component for a wind turbine. The shear web is manufactured by using a forming tool to define a flange-shaped cavity at an end of a web member. A resin is injected into the cavity and cured to form a flange cast onto the web member. The forming tool is subsequently removed from the web member to provide a component having a load-bearing flange formed from a cured resin.

Abstract: A method of joining components of a wind turbine blade involves the use of an adhesive arrestor rail positioned at the side of a joining surface of a first member of a wind turbine blade, the rail arranged to form an acute angle to a second opposed joining surface of a second member of a wind turbine blade. The arrestor rail acts to retain flowable adhesive within the bonding area between two joining surfaces, ensuring a full and complete bond is provided between the blade members. The rail provides a valve action, deflecting to allow for excess adhesive to extrude past the rail, indicating that the bonding area between the joining surfaces is filled with adhesive. The arrangement of the arrestor rail results in a tapering edge of the adhesive bond layer between two members. The arrangement provides a reduced likelihood of substantial crack formation in the adhesive bond layer.
