  • Method for manufacturing a composite material part using a hybrid cross-linked copolymer
    Patent number: 11746060
    Abstract: A method for manufacturing a part made of composite material includes forming a ceramic matrix phase in pores of a fibrous preform by pyrolysis of a cross-linked copolymer ceramic precursor, the cross-linked copolymer including a first precursor macromolecular chain of a first ceramic having free carbon, and a second precursor macromolecular chain of a second ceramic having free silicon, the first macromolecular chain being bonded to the second macromolecular chain by cross-linking bridges including a bonding structure of formula *1—X—*2; in this formula, X designates boron or aluminium, -*1 designates the bond to the first macromolecular chain and -*2 the bond to the second macromolecular chain.
    Type: Grant
    Filed: June 2, 2021
    Date of Patent: September 5, 2023
    Assignees: CENTRE NATIONAL DE LA RECHERCHE SCIENTIFIQUE, SAFRAN CERAMICS, UNIVERSITE DE BORDEAUX, UNIVERSITE DE MONTPELLIER, ECOLE NATIONALE SUPERIEURE DE CHIMIE DE MONTPELLIER
    Inventors: Marion France Hélène Schmidt, Samuel Jean-Charles Bernard, Nicolas Eberling-Fux
  • Method for manufacturing a part made of composite material using an adhesion promoter comprising a Lewis acid or a Lewis complex
    Patent number: 11746065
    Abstract: A method for manufacturing a part made of composite material in which an adhesion promoter is grafted to a coating present on the fibre surface as well as to a ceramic precursor resin. Afterwards, a ceramic matrix phase is formed in the porosity of the fibre preform by pyrolysis of the polymerised resin.
