  • Publication number: 20260116025
    Abstract: A method for manufacturing a propeller blade or vane includes the production of a fibrous blank of an airfoil-shaped structure including an inner housing, the insertion of at least one insert into the inner housing with the interposition of an adhesive film between the insert and the inner housing of the fibrous blank so as to obtain a fibrous preform, the holding of the fibrous preform in a molding cavity of an injection tooling, the injection of a resin into the molding cavity containing the fibrous preform and the transformation of the resin into a matrix by heat treatment. The method further includes, after holding of the fibrous preform in the molding cavity and before injection of the resin into the fibrous preform, a procedure of pre-consolidating the adhesive film including at least the application of a consolidation pressure in the molding cavity.

  • Patent number: 12600098
    Abstract: A method for manufacturing a vane made of composite material for a turbomachine, including the steps of three-dimensional fibre weaving and producing a fibrous preform, reinforcing an edge of the preform intended to form a leading edge of a blade of the vane, by integrating a metallic reinforcement on this edge, mounting the preform and the reinforcement in a mould, densifying the preform by a matrix to form the vane, wherein, prior to the integration of the reinforcement, the method includes a step of introducing at least one reinforcement support configured to be interposed between the reinforcement and the edge, and wherein at the densification step, the support is enveloped with the matrix to bond the edge and the reinforcement with a predefined and homogeneous minimum thickness.
