Wind turbine rotor blade with trailing edge comprising rovings

摘要

A method for manufacturing a wind turbine rotor blade having a trailing edge by Vacuum Assisted Resin Transfer Molding is described. A number of layers having fiber material are laid up onto the inner surface of a first mold part. A plurality of fiber rovings is laid up onto the number of layers at a position which forms the trailing edge of the blade. The blade is cast using Vacuum Assisted Resin Transfer Molding.
