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 *&#x2014;X&#x2014;*; in this formula, X designates boron or aluminium, -*designates the bond to the first macromolecular chain and -*the bond to the second macromolecular chain.

Method for manufacturing a composite material part using a hybrid cross-linked copolymer

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.

Method for manufacturing a part made of composite material using an adhesion promoter comprising a Lewis acid or a Lewis complex
