摘要：
A method of fastening a joining insert to a wind turbine rotor blade element (10), the method comprising the following steps:
• providing a wind turbine rotor blade element (10) of a fibre-reinforced composite material, the wind turbine rotor blade element (10) comprising a joining surface (12) and a blind hole (18), the blind hole (18) having a proximal end (20) at the joining surface (12) and a distal end (22) within the fibre-reinforced composite material,
• forming at least one channel (24) through the fibre-reinforced composite material, the at least one channel (24) connecting the distal end (22) of the blind hole (18) to a channel opening (26) at an inner and/or outer surface (14, 16) of the wind turbine rotor blade element (10),
• placing a joining insert in the blind hole (18),
• filling a space (82) between the joining insert and the blind hole (18) with a liquid plastics material in a vacuum infusion process, wherein said channel opening (26) is connected either to a liquid plastics material supply line (74) or to a process suction line (72),
• curing the liquid plastics material.
