Abstract
A layer (16) forming interphase in a material having a lamellar structure is situated 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) in such a way as to define, for those cracks which have spread through the matrix (18) and the lamellar interphase (16), a preferential propagation zone away from direct contact with the actual fibers (10).
