Abstract

La présente invention concerne un procédé de traitement d'au moins une fibre de carbure de silicium, le procédé comprenant au moins les étapes suivantes : a) formation d'une couche (22) de silice à la surface d'une fibre de carbure de silicium présentant une teneur en oxygène inférieure ou égale à 1% en pourcentage atomique, la couche de silice étant formée par mise en contact de cette fibre avec un milieu oxydant ayant une température supérieure ou égale à 50°C et une pression supérieure ou égale à 1 MPa, et b) élimination de la couche de silice formée par traitement hydrothermal de la fibre obtenue après mise en œuvre de l'étape a) dans lequel la fibre est traitée avec de l'eau à une pression comprise entre la pression de vapeur saturante et 30 MPa et à une température inférieure ou égale à 400°C.
