摘要： This invention relates to a kit for manufacturing a wind turbine blade component, a method of manufacturing such a wind turbine blade component and a wind turbine blade component thereof. The individual panel sections are interlocked via interlocking devices arranged between adjacent panel sections. The interlocking device comprises first engaging element for engaging the adjacent panel sections, wherein the interlocking device is forced into the panel section by applying force to the interlocking device.

摘要： The present invention relates to a method of manufacturing a wind turbine blade, comprising arranging one or more layers of fibre material and a preform in a mould (66), injecting the one or more layers of fibre material and the preform (76) with a curable resin, and curing the resin. The preform (76) is impregnated with a curing promoter such that the concentration of curing promoter varies spatially within the preform.

摘要： The present invention relates to a method and system for manufacturing a wind turbine blade. The method comprising the steps of forming a cured blade element (102) of a first blade shell, forming a cured blade element (102) of a second blade shell, transferring the cured blade element (102) of the first blade shell to a first cradle (92), and transferring the cured blade element (102) of the second blade shell to a second cradle (94). Each cradle comprises a mould body (96, 98) having a moulding surface for abutting against a surface of the cured blade element to advantageously form a seal therebetween.
