1. A method for producing a rotor blade of a wind turbine, the method comprising:
providing at least two different components of the rotor blade, wherein the at least two different components comprise a first half-shell and a second half-shell;
providing a structure between the first half-shell and the second-half shell, wherein the structure comprises a structural element, a resistive element, and a resin strip, wherein the resistive element is disposed between, and is embedded in both, the structural element and the resin strip, wherein the resin strip is in direct mechanical contact with the first half-shell, wherein the structural element comprises fiber composite material, and wherein the resistive element comprises copper or carbon fibers;
placing a mold on, and in direct mechanical contact with, an outer surface of the first half-shell;
simultaneously: (i) energizing the resistive element so that the resistive element applies heat to the resin strip to soften the resin strip and (ii) applying pressure to the mold in a direction toward the first half-shell; and
after completion of said simultaneously energizing the resistive element and applying pressure to the mold, cooling the resin strip and removing the mold.
