Abstract
A spar cap assembly is for a wind turbine rotor blade. The spar cap assembly has a spar cap reinforced with carbon fibers, comprising a lightning conductor, which is arranged so as to run along the spar cap, and at least one potential-equalizing element, which establishes an electrical connection between the spar cap and the lightning conductor. The carbon fibers of the spar cap, the lightning conductor and the at least one potential-equalizing element are embedded in a common polymer matrix and are configured as a prefabricated assembly for integration into a wind turbine rotor blade half-shell after the curing of the polymer matrix.
