    Abstract: The present invention relates to a reinforcing structure, such as a reinforcing structure for reinforcing a wind turbine blade, comprising: a first composite element layer comprising at least two carbon fibre reinforced composite elements; a second composite element layer comprising one or more carbon fibre reinforced composite elements; an interlayer sandwiched at least partly between the first and the second composite element layer, the interlayer comprising an electrically conductive portion and a non-conductive portion surrounding the conductive portion, the conductive portion abutting exactly two of the carbon fibre reinforced composite elements comprised in the first composite element layer. A method for manufacturing such a structure is also provided.

    Abstract: The present invention relates to a method for manufacturing a wind turbine blade part. The method comprises providing one or more wind turbine blade components including a wind turbine blade component comprising a fibre material element, an electrically conductive element, a magnetic field generator for generating an Eddy current in the electrically conductive element; arranging the electrically conductive element, the magnetic field generator, and the fibre material element such that at least a part of the fibre material element is positioned between the electrically conductive element and the magnetic field generator; generating an Eddy current in the electrically conductive element using the magnetic field generator; generating, using a magnetic sensor, a signal representing a magnetic field induced by the generated Eddy current, and forming the wind turbine blade part by assembling the wind turbine blade components.
