Abstract
A method of manufacturing a shell construction part of a wind turbine blade, the shell construction part being made of a fibre reinforced polymer material including a polymer matrix and fibre reinforcement material embedded in the polymer matrix. The method comprises the steps of a) providing a forming structure comprising a mould cavity and having a longitudinal direction, b) placing the fibre reinforcement material in mould cavity, c) providing a resin in the mould cavity simultaneously with and/or subsequently to step b), and d) curing the resin in order to form the composite structure, wherein at least 20% by volume of the fibre reinforcement material consists of metallic wires.
