Title (EN) CMC WITH MULTIPLE MATRIX PHASES SEPARATED BY DIFFUSION BARRIER
(FR) CMC AUX MULTIPLES PHASES MATRICIELLES SÉPARÉES PAR DES BARRIÈRES DE DIFFUSION
Abstract: front page image
(EN)A ceramic matrix composite (CMC) material (10) with increased interlaminar strength is obtained without a corresponding debit in other mechanical properties. This is achieved by infusing a diffusion barrier layer (20) into an existing porous matrix CMC to coat the exposed first matrix phase (19) and fibers (12), and then densifying the matrix with repeated infiltration cycles of a second matrix phase (22). The diffusion barrier prevents undesirable sintering between the matrix phases and between the second matrix phase and the fibers during subsequent final firing and use of the resulting component (30) in a high temperature environment.
(FR)La présente invention concerne un matériau composite à matrice céramique (CMC) (10) à meilleure résistance interlaminaire qui est obtenu sans altération correspondante d’autres propriétés mécaniques. On le produit en insérant une couche barrière de diffusion (20) au sein d’une matrice poreuse CMC en place pour recouvrir la première phase de matrice exposée (19) ainsi que les fibres (12), ce faisant en densifiant la matrice par des cycles d’infiltration répétés de la seconde phase de matrice (22). La barrière de diffusion permet de prévenir un frittage non voulu entre les phases matricielles de même qu’entre la seconde phase de matrice et les fibres durant l’opération de chauffage finale ultérieure ou durant l’emploi du composant obtenu (30) dans un environnement à haute température.
