Title (EN) THREE-DIMENSIONAL PRINTING OF A CERAMIC FIBER COMPOSITE FOR FORMING COOLING DESIGNS IN A COMPONENT
(FR) IMPRESSION TRIDIMENSIONNELLE D'UN COMPOSITE DE FIBRES CÉRAMIQUES DESTINÉE À FORMER DES STRUCTURES DE REFROIDISSEMENT DANS UNE PIÈCE
Abstract:
(EN) Processes and systems are described herein for forming cooling channels (314) within a ceramic matrix composite component (300). The process introducing a ceramic material (18, 32) into a solid fiber material (14, 46) to produce a ceramic fiber composite (24, 48) and depositing the ceramic fiber composite (24, 48) in a predetermined pattern to form at least a portion of the ceramic matrix composite component (300) having a plurality of internal cooling channels (314) formed therein.
(FR) L'invention concerne des procédés et des systèmes destinés à former des canaux de refroidissement (314) au sein d'une pièce composite à matrice céramique (300). Le procédé consiste à introduire un matériau céramique (18, 32) dans un matériau de fibres solides (14, 46) en vue de produire un composite de fibres céramiques (24, 48) et à déposer le composite de fibres céramiques (24, 48) dans un motif prédéterminé en vue de former une pluralité de canaux de refroidissement internes (314) dans au moins une partie de la pièce composite à matrice céramique (300).
