A FIBER LAY-UP, A BLADE ROOT FOR A WIND TURBINE ROTOR BLADE, A WIND TURBINE ROTOR BLADE AND A METHOD FOR PRODUCING A WIND TURBINE ROTOR BLADE

摘要

A fiber lay-up for a blade root of a wind turbine rotor blade, comprising a spar cap section and at least one side section that laterally branches from and runs at least partly parallel to the spar cap section. This has the advantage that an evenly load transfer from the root bushings to the beam or spar cap of the wind turbine rotor blade is ensured by the branching side sections of the fiber lay-up.
