PROCÉDÉ DE TRAITEMENT DE FIBRES DE CARBURE DE SILICIUM
A method of treating at least one silicon carbide fiber, the method including a) putting at least one silicon carbide fiber presenting an oxygen content that is less than or equal to 1% in atomic percentage into contact with an oxidizing medium in order to transform the surface of the fiber chemically and form a surface layer of silica; b) eliminating the resulting silica layer by putting the fiber obtained after performing step a) into contact with an acid liquid medium comprising at least hydrofluoric acid; and c) depositing an interphase layer on the surface of the fiber obtained after performing step b).
