1. A method for manufacturing a part made of a first ceramic or made of carbon, consolidated by a second ceramic, having a determined geometry, wherein the following successive steps are carried out:
a) a preform made of an organic polymer is manufactured, the preform having the same geometry as the part to be manufactured;
b) the preform made of an organic polymer is impregnated with a first-ceramic precursor resin or a carbon precursor resin;
c) the first-ceramic precursor resin or the carbon precursor resin is cross-linked and/or polymerised and then pyrolysed;
d) optionally, steps b) and c) are repeated;
whereby, at the end of step c) or step d), a part made of a first ceramic or made of carbon, having the same geometry as the part to be manufactured, is obtained;
e) the second ceramic is deposited onto the part made of a first ceramic or made of carbon obtained at the end of step c) or step d), by a Chemical Vapour Deposition (CVD) method or a Chemical Vapour Infiltration (CVI) method; and
wherein no second ceramic is present in steps a)-d).
