Abstract
A method for manufacturing a part from a first ceramic or from carbon, consolidated by a second ceramic, having a determined geometry, that involves carrying out the following sequence of steps: a) manufacturing a preform made from an organic polymer; b) impregnating the preform made from an organic polymer with a resin that is a precursor of the first ceramic or a resin that is a precursor of carbon; c) crosslinking and/or polymerising, then pyrolysing the resin that is a precursor of the first ceramic or the resin that is a precursor of carbon; to obtain a part made from a first ceramic or from carbon having the same geometry as the part to be manufactured; e) depositing the second ceramic on the part made from a first ceramic or from carbon by means of a chemical vapour deposition or CVD process or a chemical vapour infiltration or CVI process.
