A kit of materials 60 for arranging in a wind turbine blade mould 80 to form part of a wind turbine blade shell includes a base layer 62 of fibrous fabric and a core layer of core (e.g foam) material. The layers of the kit are shaped to form part of a wind turbine blade shell and are attached together such that the kit can be arranged in the blade mould as a single unit. Preferably the kit comprises one or more under-layers and one or more over-layers and the layers of the kit are stitched together. The core layer preferably comprises a plurality of core panels spaced apart to define spanwise channels 68. The core panels may comprise mating features 72a for mating with complementary mating features 72b of core panels on adjacent kits to connect the panels together. A method of making a wind turbine blade preferably comprises pre-assembling a plurality of kits outside the mould 88 and transferring them to the mould. The method may comprise arranging one or more reinforcing structures, such as spar caps, in the spanwise channels between the core panels. |
