Patent ID: 7938625

Claim:
A method of manufacturing a fibre-reinforced blade for a wind energy plant, said blade being configured with at least a blade shell and means for conducting to earth adapted for conducting a lightning current to an earth connection; and wherein the method is characterised in comprising the steps of distributing and attaching segmented conductor means essentially flush with the external surface of the blade shell; and further characterised in comprising the steps of: a) arrangement of segmented conductor means on a mould of the blade; b) laying of fibres on the mould, including on top of the conductor means; c) attachment of the fibres and the conductor means by resin; whereby the segmented conductor means are formed integrally with the blade; and wherein: the conductor means are electrically conductive particles that have an expanse of between 0.05 and 10 mm; said conductive particles are separated to avoid the occurrence of a continuous conductor; and the conductor means are distributed in at least one path, said path having a width of between 3 and 50 mm; whereby in the event of a lightning strike to form an ionized passage outside the blade adjacent to the conductor means for guiding a lightning current in the passage to the means for conducting current to earth.
