Abstract: A hybrid material mat for use in the manufacture of fibre-composite articles, in particular parts for wind turbine blades, is described. The mat comprises a plurality of glass fibre rovings provided on top of a relatively thin planar substrate of carbon fibres. Such a hybrid mat construction provides for an improvement in the structural properties of a component manufactured using the mat, as well as allowing for ease of handling and manufacturing of both the mat itself and the component.

Abstract: A method of manufacturing a wind turbine blade component in form of a shear web is described. The method comprising the steps of: a) providing a pre-manufactured shear web body having a first side and a second side as well as a first end and a second end; b) providing a first pre-formed web foot flange comprising a fibre-reinforcement material; c) arranging a first fibre layer from the first pre-formed web foot flange and to a part of the first side of the shear web body; d) arranging a second fibre layer from the first pre-formed web foot flange and to a part of the second side of the shear web body; e) supplying a resin to said first fibre layer and second fibre layer simultaneous with or subsequent to steps c) and d); and f) allowing the resin to cure so as to form the shear web.

Abstract: A serrated panel (70) for a wind turbine blade is disclosed. The panel (70) is configured to be attached to the trailing edge of a blade to form a plurality of serrations (71) at the trailing edge of the blade. The serrated panel comprises a base part (72) for attaching the panel (70) to the trailing edge of the blade. An exterior surface (78) of the base part comprises a corrugated surface in direction between longitudinal ends of the panel such that the exterior surface comprises crests (82) aligned substantially with midpoints of bases (80) of the serrations (71) and valleys (83) aligned substantially between serrations (71).

IPC: F03D1/06

Abstract: A wind turbine blade having a surface mounted device attached thereto via at least a first attachment part, which is connected to a part of the device. The first attachment part comprises an outer attachment part providing a first bonding connection between the device and the surface of the blade, wherein the first bonding connection is an elastic bond, and an inner attachment part providing a second bonding connection between the device and the surface of the blade, wherein the second bonding connection has a structural bond. The structural bond prevents the surface mounted device from creeping and the elastic bond region relieves stresses on the bond line, such as peel stresses, whereby the surface mounted device is less likely to be ripped off the surface of the blade due to forces affecting the device or the blade.
