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 ZrOCphase, 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 Cto Cpolyalcohol modified by linking the oxygen atom of at least one alcohol function to a group of formula —Zr—R, the substituents R being identical or different, and R being selected from: —H, Cto Ccarbon chains and halogen atoms.
