The composite material has multiple interphase between the reinforcing fibers and ceramic matrix refractory

摘要

A layer 16 forming an interphase layer of a material having a lamellar structure is located between the fibers of the texture and the matrix, and at least one layer 14 forming control interphase is situated between the surface of the fibers 10 and the lamellar interphase 16 so as to define, for cracks propagated through the matrix 18 and the lamellar interphase 16, a preferential progression zone out of the direct contact with the same fibers 10.
