摘要
A method of manufacturing a composite laminate structure of a wind turbine blade part is performed by resin transfer moulding. The fibre-reinforcement material is impregnated with liquid resin in a mould cavity which includes a rigid mould part having a mould surface defining a surface of the wind turbine blade part. The method includes alternately stacking on the rigid mould part: i) a number of fibre-reinforcement layers including electrically conductive fibres and ii) a flow strip layer in form of a layer of flow strips having a strip width and which are arranged so as to form voids having a void width between two juxtaposed strips. The method includes sealing a second mould part against the rigid mould part in order to form the mould cavity, optionally evacuating the mould cavity, supplying a resin to the mould cavity, and curing the resin to form the composite laminate structure.
