CMC for Aero-Gas Turbines

The efficiency and thus the energy efficiency of aircraft gas turbines increases with the operating temperature. In this respect, ceramics with their high operating temperatures are fundamentally superior to the metal alloys that have been predominantly used to date. The lower density of ceramics also has an advantageous effect on fuel consumption. In the hot area of aircraft gas turbines, high mechanical and thermomechanical stresses prevail. Conventional monolithic ceramics do not have the necessary damage tolerance and thermal shock resistance. for use in this area. Fibre-reinforced ceramics (Ceramic Matrix Composites = CMC), on the other hand, can be equipped with a high fracture toughness - similar to metals. In aircraft gas turbines, CMC components are used, for example, as guide vanes or rotor blades, sealing segments or mixers in the exhaust gas jet.
