1. A method for drying a blank of a part made of a carbon/carbon composite material impregnated with a sol-gel solution, the solution comprising a solvent and one or more compounds, in a system forming an oven, wherein the system comprises:
a chamber configured to receive the blank,
gas circulation means configured to selectively enable a gas to be circulated between a gas outlet of the chamber and a gas inlet of the chamber,
gas desaturation means being configured to selectively enable at least partial desaturation of the gas in a solvent,
and the method comprises:
gelling the solution so as to form a gel within the blank disposed in the chamber by heating the chamber, the circulation means and the desaturation means being deactivated, so as to restrict circulation and desaturation of the gas in a solvent, and
drying the gel within the blank by heating, the circulation means and the desaturation means being activated, so as to enable circulation and desaturation of the gas in a solvent.
