摘要
A wind turbine rotor blade includes an elongate body having a root end configured to be coupled to a rotor hub of a wind turbine. The rotor blade further includes a connection joint at the root end for connecting the rotor blade to the rotor hub. The connection joint includes a plurality of connecting elements integrated into the root end of the rotor blade and including an eye that defines a bore through the root end of the rotor blade. The connecting elements may be formed from folded fiber rovings wherein the fold forms the eye. A method of making a rotor blade having the connecting element integrated therein, and a method of making the connecting elements are also disclosed.
