Abstract
(DE)
Die Erfindung betrifft ein Formteil aus oxidischer Faserverbundkeramik, im Folgenden auch „CMC-Formteil" genannt, wie es beispielsweise in einer Turbinenkomponente, einem Brenner und/oder in einem Abgasstrang einsetzbar ist, insbesondere eines, bei dem kritische Bereiche des Formteils verstärkt sind, die während des Betriebs besonders belastet und/oder aufgrund ihrer Geometrie besonders empfindlich sind, sowie ein Verfahren zur Herstellung derartig verstärkter Bauteile. Durch die vorliegend beschriebene Erfindung wird ein technisches Konzept beschrieben, durch das beispielsweise Turbinenkomponenten oder andere CMC-Formkörper, insbesondere solche mit Bereichen, die einen spitzen Winkel formen und/oder Bereichen, die einen geringen Krümmungsradius aufweisen, mit verbesserter Qualität, insbesondere mit höheren Strukturstabilitäten der kritischen und besonders Schädigungsanfälligen Stellen herstellbar sind.
(EN)
The invention relates to a moulded part made oxide composite fibre ceramic, referred to below as a "CMC moulded part", such as can be used, for example, in a turbine component, in a burner and/or in an exhaust gas system, in particular one in which critical regions of the moulded part which are particularly loaded during operation and/or are particularly vulnerable due to their geometry are reinforced. The invention further relates to a method for producing such reinforced structural parts. The invention relates to a technical concept by which, for example, turbine components or other CMC moulded bodies, in particular those having regions which form an acute angle and/or regions which have a small radius of curvature, can be produced with improved quality, in particular with higher structural stability of the critical and particularly damage-prone points.
(FR)
L’invention concerne une pièce moulée en céramique composite renforcée de fibres oxydée, dénommée aussi ci-après « pièce moulée CMC », telle que par exemple utilisable dans un composant de turbine, dans un brûleur et/ou dans une ligne de gaz d'échappement, en particulier une pièce dans laquelle des zones critiques de la pièce moulée, qui sont soumises à une charge particulièrement élevée durant le fonctionnement et/ou qui sont particulièrement sensibles en raison de leur géométrie, sont renforcées, ainsi qu’un procédé pour la fabrication de telles pièces renforcées. La présente invention décrit un concept permettant la fabrication de composants de turbine ou d’autres pièces moulées CMC, en particulier de pièces avec des zones formant un angle aigu et/ou des zones qui présentent un faible rayon de courbure, avec une qualité améliorée, en particulier avec une stabilité structurelle plus élevée des emplacements critiques et particulièrement sensibles à l’endommagement.
