Abstract
A method for producing a part made of ceramic matrix and ceramic fibers composite material. It comprises: the formation of a fibrous preform by intertwining threads constituted of ceramic material fibers on a contact surface of a support element reproducing the internal and/or external shape of the part to be produced; the partial densification of the fibrous preform at a temperature below the melting temperature of the material of the support element and below the melting temperature of the material of the fibers of the preform, said partial densification resulting in a consolidated fibrous preform comprising a matrix volume fraction above 5% and at the most equal to 40% of the matrix volume of the part to be produced; the removal of the support element from the consolidated fibrous preform by chemical attack of the contact surface of the material of the support element; the densification of the consolidated preform, carried out at a temperature below the melting temperature of the fibers of said preform.
