Abstract
The present disclosure provides a method of manufacturing a composite laminate structure of a wind turbine blade part by means of resin transfer moulding, preferably vacuum-assisted resin transfer moulding. In a resin transfer moulding, fibre-reinforcement material is impregnated with liquid resin in a mould cavity. The mould cavity comprises rigid mould part having a mould surface defining a surface of the wind turbine blade part.The method comprises alternately stacking on the rigid mould part: The flow-enhancing fabric layer further comprises filaments or bundles of fibres made of a second material, which is an electrically conductive material and which are arranged and configured to provide a conductive path from first electrically conductive fibres of a first fibre-reinforcement layer on a first side of the flow-enhancing layer to second electrically conductive fibres of a second fibre-reinforcement layer on a second side of the flow-enhancing layer.
