Abstract
The present invention relates to a method of molding a shell part of a wind turbine blade. The method involves attaching one or more fastening elements (63) onto a molding surface, each fastening element (63) comprising a support layer (64) with an upper face (66) and a lower face (68), and one or more spikes protruding from the upper face of the support layer (64). Fiber plies are then successively laid out into the molding cavity (78) such that each ply is anchored to one or more of said spikes. The fiber plies are then contacted with a polymer material to produce a shell part comprising a fiber reinforced composite material. The invention also relates to a shell part of a wind turbine blade obtainable by the method and to a fastening element for use in said method.
