An inseparable assembly (42) includes a body (80) having a first surface (82) and a second surface (88). The body (80) includes an oxide-based ceramic matrix composite material having a first predetermined ductility. The assembly (42) further includes a crack (128) extending through the body (80) between the first surface (82) and the second surface (88), and a patch (150) bonded to at least one of the first surface (82) and the second surface (88) overlapping at least a portion of an edge (134) of the crack (128). The patch (150) includes a second material having a second predetermined ductility that is greater than the first ductility.
Ensemble inséparable (42) comprenant un corps (80) doté d'une première surface (82) et d'une seconde surface (88). Le corps (80) comprend un matériau composite à matrice céramique à base d'oxyde doté d'une première ductilité prédéterminée. L'ensemble (42) comprend de plus une fissure (128) traversant le corps (80) entre la première (82) et la seconde surface (88) ainsi qu'une pièce (150) adhérant au moins à la première (82) ou à la seconde surface (88) et chevauchant au moins une partie d'un bord (134) de la fissure (128). La pièce (150) est faite d'un second matériau doté d'une seconde ductilité prédéterminée, supérieure à celle du matériau composite.
