  • 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).
    Type: Grant
    Filed: March 13, 2018
    Date of Patent: April 11, 2023
    Assignee: ARKEMA FRANCE
    Inventors: Virginia Bozsak, Guillaume R. Cledat, Pierre Gerard, Mark Hiemstra, Henk Minnema, Dirk Jan Kootstra
  • Process for manufacturing thermoplastic polymer composite parts, and object obtained by said process
    Patent number: 11623412
    Abstract: The invention relates to a process (100) for manufacturing an object (1) made of thermoplastic polymer composite from at least two parts (10) made of thermoplastic polymer composite, said thermoplastic polymer composite comprising a fibrous reinforcement and a thermoplastic polymer matrix, said process comprising the steps of: arranging (120) the two parts (10) made of thermoplastic polymer composite adjacently or overlapping at an assembly interface zone (11), and heating (130) to melt the thermoplastic polymer matrix at said assembly interface zone (11), so as to form an object (1) made of thermoplastic polymer composite comprising a welded interface (12).
