  • Publication number: 20240068437
    Abstract: The present invention relates to a method of manufacturing a wind turbine blade shell component (38), the method comprising the steps of providing a plurality of pultrusion plates (64), arranging the pultrusion plates (64) on blade shell material (89) in a mould (77) for the blade shell component, and bonding the pultrusion plates (64) with the blade shell material to form the blade shell component, wherein each pultrusion plate (64) is formed of a pultrusion fibre material comprising glass fibres and carbon fibres. The invention also relates to a reinforcing structure for a wind turbine blade, the reinforcing structure comprising a plurality of pultrusion plates according to the present invention.

  • Publication number: 20070253827
    Abstract: A method of manufacturing a fibre-reinforced blade for a wind energy plant is presented, which blade is configured with at least a blade shell and means for conducting to a lightning current to an earth connection. Novel aspects of the method comprise that the blade is provided with segmented conductor means that are configured for conducting a lightning current outside the blade to the means for conducting to earth; and wherein the conductor means are distributed and secured at the external surface of the blade shell in such a manner that the conductor means are essentially flush with the external surface of the blade shell. When the segmented conductor means are distributed and attached at the external surface of the blade shell, the lightning current will not have to be conducted through the conductor means, but rather they are conducted in a ionised passage in the air above the conductor means.

  • Publication number: 20070193491
    Abstract: The invention relates to a method of manufacturing a fibre mat adapted for use in the manufacture of a fibre-reinforced device, said fibre mat comprising at least two essentially longitudinally extending and parallel batches of fibres. Novel aspects of the method according to the invention involves that the method comprises that the batches are joined by holder means that span above or below each batch, whereby the holder means impart an influence to each batch which is essentially symmetrical about an axis situated longitudinally between the batches. A symmetrical influence about an axis longitudinally between the batches accomplishes that influence from one side is matched by influence from an opposite side. Hereby it is prevented that the batch will undulate. Simultaneously the batches are clearly separated, whereby resin is more easily conducted longitudinally of the batches.
