Abstract
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 (), injecting the one or more layers of fibre material and the preform () with a curable resin, and curing the resin. The preform () is impregnated with a curing promoter such that the concentration of curing promoter varies spatially within the preform.
