A process which comprises: a molding formation step in which a fibrous molding is formed from short fibers of silicon carbide having a heat resistance of 1,000~C or higher; a sol-gel solution preparation step in which a sol-gel solution containing a heat-resistant compound having a heat resistance of 1,000~C or higher is prepared; an impregnation/drying/calcinations step in which the fibrous molding is impregnated with the sol-gel solution, dried, and calcined; and a crystallization step in which the impregnated, dried, and calcined fibrous molding is crystallized.
Un procédé qui comprend : une étape de formation d~un moulage au cours de laquelle est formé un moulage en fibres à partir de fibres courtes de carbure de silicium avec une résistance à la chaleur de 1 000 ·C ou plus ; une étape de préparation d~une solution sol-gel dans laquelle est préparée une solution sol-gel contenant un composé thermorésistant ayant une résistance à la chaleur de 1 000 ·C ou plus ; une étape d~imprégnation/séchage/calcination au cours de laquelle le moulage en fibres est imprégné de la solution sol-gel, séché et calciné ; et une étape de cristallisation au cours de laquelle le moulage imprégné, séché, et calciné est cristallisé.
