Abstract:
1. A method of manufacturing a root section of a rotor blade of a wind turbine, comprising: assembling a plurality of supporting rods, each having an interface section for connecting to a hub interface of the wind turbine in an essentially circular shape such that there are gaps between the supporting rods; arranging a plurality of first fibers in the gaps which the plurality of first fibers are physically and/or chemically compatible with an injection material; placing a first molding tool along an outer surface of the circular shape and a second molding tool along an inner surface of the circular shape; and treating the injection material so that it bonds with the plurality of first fibers such that the injection material is made sufficiently liquid to migrate between the fibers and then be cured in order to firmly bond with them, wherein space between the outer surface of the circular shape and the first molding tool and/or between the inner surface of the circular shape and the second molding tool is filled with a plurality of second fibers which are physically and/or chemically compatible with the injection material.
