The invention relates to a method for producing a rotor blade by arranging foam (23, 24) in a semi-finished product, introducing resin into the foam-containing semi-finished product, and curing the introduced resin while heat is dissipated and a curing temperature distribution is obtained, a first foam (23) being arranged in regions of the semi-finished product with a higher curing temperature, and a second foam (24) in regions with a lower curing temperature, and a foam with a higher temperature resistance than the second foam (24) being chosen as the first foam (23).
