  • Patent number: 9541068
    Abstract: A method for making a wind turbine member wherein a plurality Of components are arranged in a mold. The inner side of the mold determines a surface of the wind turbine member. The components are connected to one another. At least one of the components is a prefabricated structural element which has a fixed geometry with an outer surface. The prefabricated structural element has a positioning projection protruding out of the outer surface and the mold has, on its inner side, a positioning receptacle. The positioning projection is inserted positively into the positioning receptacle to determine the disposition of the prefabricated structural element in the mold.

  • Patent number: 9108376
    Abstract: A method for making a wind turbine rotor blade half shell includes arranging a fibrous material in a mold, which has an inner side predetermining an aerodynamic surface of the half shell and has a pinching edge defining the profile of a trailing edge of the half shell. A liquid plastics material surrounding the fibrous material is cured. An insert is arranged in relation to the mold in a predetermined position, in which a surface of the insert and a bordering portion of the inner side of the mold conjointly define an acute angle tapering toward the pinching edge, so that a thinly tapering trailing edge of the half shell is formed between the surface of the insert and the bordering portion.

  • Patent number: 8992819
    Abstract: 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.

  • Publication number: 20130049249
    Abstract: Method for producing a wind turbine rotor blade part with a carbon fiber-reinforced main spar cap. The method includes: inserting a layer of a first fibrous material into a mold, wherein the fibrous material extends over a first width, inserting a first distribution medium and a plurality of layers of a carbon fiber material into the mold above the first distribution medium, wherein the layers of the carbon fiber material extend over a second width smaller than the first width, so that connecting sections of the first fibrous material protrude beyond the carbon fiber material on both sides thereof, inserting a second distribution medium and arranging an extraction channel above the carbon fiber material, arranging sprue channels in the region of the connecting sections, closing the mold and extracting the air therefrom via the extraction channel and feeding liquid plastics material that hardens through the sprue channels.
