  • A METHOD FOR PRODUCING A ROTOR BLADE OF A WIND TURBINE
    Publication number: 20230415424
    Abstract: A method for producing a rotor blade of a wind turbine includes the following steps: a) providing at least two different components of the rotor blade, b) placing a resistive element between the components, c) placing a thermoplastic or weldable thermoset resin between the components, d) energizing the resistive element so that the resistive element applies heat to the thermoplastic or weldable thermoset resin to melt or to soften it, and e) joining the components together by means of the molten or softened thermoplastic or weldable thermoset resin.

  • Wind turbine blade made of thermoplastic polymer composite, part of said blade and production method
    Patent number: 11624347
    Abstract: The invention relates to a wind turbine blade (1) comprising an outer casing formed at least in part of panels (3) of thermoplastic polymer composite, defining a leading edge (4) and a trailing edge (5) of the wind turbine blade, and at least one longitudinal stiffening member (6) made of polymer composite, extending along a longitudinal axis (A) of the wind turbine blade inside said wind turbine blade (1), said stiffening member (6) being arranged between at least one panel defining the leading edge (4) and at least one panel defining the trailing edge (5), characterized in that the thermoplastic polymer composite comprises a fibrous reinforcement and a (meth)acrylic thermoplastic polymer matrix and in that at least one panel (3) of thermoplastic polymer composite is connected to the stiffening member (6) by a weld-type interface (7).
