Abstract
After making a carbon fiber preform and prior to completing densification of the preform with a carbon matrix, impregnation is performed with a liquid formed of a sol-gel type solution and/or a colloidal suspension enabling one or more zirconium compounds to be dispersed. The impregnation and the subsequent treatment, up to obtaining the final part, are performed in such a manner as to have, in the final part, grains or crystallites of one or more zirconium compounds presenting a fraction by weight lying in the range 1% to 10% and of composition having at least a majority of the ZrOCtype with 1≦x≦2 and 0≦y≦1.
