Abstract
Official abstract text for this publication.
Method for producing a wind turbine rotor blade part with a prefabricated main spar cap, comprising the following steps: providing a mold having a blade-root end and with a blade-tip end, inserting at least one outer root reinforcement layer ( 28 ) made of a fibrous material into the mold, arranging the prefabricated main spar cap on the at least one outer root reinforcement layer, arranging, in the mold, at least one inner root reinforcement layer made of a fibrous material on the main spar cap, closing the mold, extracting the air from the mold through at least one extraction channel arranged at a lateral distance from the main spar cap, feeding a liquid plastics material through a first sprue channel which has a plurality of outlet openings below the main spar cap, feeding a liquid plastics material through a second sprue channel which has a plurality of outlet openings above the main spar cap.
