Abstract

Abstract Translated from French Une couche (16) formant interphase en un matériau à structure lamellaire est située entre les fibres de la texture et la matrice, et au moins une couche (14) formant interphase de contrôle est située entre la surface des fibres (10) et l'interphase lamellaire (16) de manière à définir, pour des fissures propagées à travers la matrice (18) et l'interphase lamellaire (16), une zone de cheminement préférentiel hors du contact direct avec les fibres-mêmes (10). An interphase layer (16) of lamellar structure material is located between the texture fibers and the matrix, and at least one interphase control layer (14) is located 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 path zone out of direct contact with the fibers themselves (10).
