  • Process for manufacturing a composite friction component
    Patent number: 11530727
    Abstract: A process for manufacturing a friction component made of composite material, includes the densification of a fibrous preform of carbon yarns by a matrix including at least pyrocarbon and at least one ZrOxCy phase, where 1?x?2 and 0?y?1, the matrix being formed by chemical vapor infiltration at least from a first gaseous precursor of pyrocarbon and a second gaseous precursor including zirconium, the second precursor being an alcohol or a C1 to C6 polyalcohol modified by linking the oxygen atom of at least one alcohol function to a group of formula —Zr—R3, the substituents R being identical or different, and R being selected from: —H, C1 to C5 carbon chains and halogen atoms.

  • Method for producing a pyrolytic carbon with predetermined microstructure
    Patent number: 11530166
    Abstract: A process for manufacturing pyrocarbon, includes forming pyrocarbon by a calefaction process from at least one C2 to C6 alcohol or polyalcohol precursor, the precursor being ethanol, rough laminar pyrocarbon being obtained by imposing a temperature of between 1250° C. and 1325° C. during calefaction.
