Abstract
A method of fastening a joining insert to a wind turbine rotor blade element, the method including: providing a wind turbine rotor blade element of a fiber-reinforced composite material, the rotor blade element having a joining surface and a blind hole, the blind hole having a proximal end at the joining surface and a distal end within the fiber-reinforced composite material; forming a channel through the fiber-reinforced composite material, the channel connecting the distal end of the blind hole to a channel opening at an inner and/or outer surface of the rotor blade element; placing a joining insert in the blind hole; filling a space between the joining insert and the blind hole with a liquid plastics material in a vacuum infusion process, wherein the channel opening is connected either to a liquid plastics material supply line or to a process suction line; curing the liquid plastics material.
