Abstract: A method for manufacturing a preform building element used for building a wind turbine rotor blade, that is manufactured from one or more fiber mat components and at least one further component arranged on a molding surface of a mold, wherein one or more fiber mat components are arranged one after the other on the further component and/or on previously arranged fiber mat components, wherein the fiber mat component is laid out at least sectionally on the respective directly subjacent component with a moving boundary of a contact area, at which the laid out fiber mat comes into contact with the subjacent component, during laying out of the or each fiber mat component, a binding agent is applied at least sectionally to the boundary and/or a binding agent supplied in the laid-out fiber mat component and/or in the subjacent component is activated at least sectionally at and/or behind the boundary.

Abstract: A Mold arrangement for producing a preform element of a wind turbine blade is provided, including a mold carrier with a receiving section having a three-dimensional receiving surface for receiving a mold element and at least one transferable and flexible plate-like mold element adapted to receive preform building material and arrangeable on the receiving surface, which flexible mold element adapts to the three-dimensional geometry of the receiving surface when positioned on the receiving surface.

Abstract: A method for manufacturing a preform element made of preform building material for a wind turbine blade is provided, wherein the preform building material is arranged in a sealed vacuum bag arranged in a shape defining mold, whereafter the vacuum bag is evacuated for vacuum fixating the preform building material in the shape defined by the mold.

Abstract: A method for manufacturing at least a part of a wind turbine blade in a resin-based casting process using a mold is provided, wherein at least one preform element, at least one further preform element and at least one laminate supporting element are arranged in the mold, wherein the preform element is arranged on a molding surface of the mold and extends over a section of the circumference of the blade part to be manufactured, wherein the laminate supporting element is arranged on the preform element and the further preform element is arranged on the laminate supporting element, wherein the preform element and the further preform element extend over the entire circumference of the blade part to be manufactured, wherein the preform elements are at least partly infused with a resin for casting of the blade part.

Abstract: A carrier plate for a preform manufacturing arrangement for producing a preform element for a wind turbine blade is provided, adapted to receive either a mold element with preform building material on a receiving surface or to directly receive the preform building material on the receiving surface, with the carrier plate having a rectangular shape with a longer longitudinal axis and a shorter transverse axis, wherein the carrier plate is flexible around the longitudinal axis but stiffened against bending around the transverse axis, and stretchable along the transverse axis but stiff along the longitudinal axis.

Abstract: A method for manufacturing of a wind turbine blade component is provided, including the steps: providing a fabric material and at least one binding agent, cutting the fabric material into a plurality of fabric sheets using a fabric cutting tool and arranging at least one stack of the cut fabric sheets on at least one preform mold tool, wherein the binding agent is arranged in and/or in between the stacked fabric sheets, consolidating the stack of fabric sheets, wherein the stack of consolidated fabric sheets forms a preform part, arranging at least one preform part inside a resin injection mold tool, injecting resin into the preform part, curing the resin, arranging the cured part on a holding means, and treating the cured part using at least one treatment tool for forming the wind turbine blade component.

Abstract: A mold arrangement for producing a preform element of a wind turbine blade includes a mold carrier and a plate- or tray-like mold element arranged at the mold carrier with a form defining mold surface adapted to receive preform building material, a first heating device arranged below the mold element for heating the preform building material from below the mold element, and a second heating device for heating the preform building material from above.

Abstract: An oven, adapted to heat preform building material arranged on a transportable, plate-like mold carrier for producing preform building elements used for building a rotor blade of a wind turbine is provided, with a housing adapted to receive several covered mold carriers and having a closable front and a closable rear opening for loading and unloading the mold carriers, wherein the housing includes several receiving means arranged in different levels with each receiving means being adapted to receive at least one mold carrier, and with several heating means assigned to the several intermediate spaces between vertically adjacent mold carriers and the spaces below and/or above the top and bottom mold carrier and adapted to heat the preform building material.

Abstract: A method for manufacturing preforms for a wind turbine blade is provided, with the steps: providing a mold p and arranging a preform building material p in a transferable mold element removably arranged on a mold carrier, fixating the preform building material in the mold element, removing the mold element with the fixed preform building material from the mold carrier and transferring it into a heating means, heating the preform building material for producing the preform, removing the mold element with the preform from the heating means and cooling the preform.
