for high-temperature applications in aerospace and energy
Future energy efficient, green aero-engines as well as land-based gas turbines demand new light-weight materials showing the high temperature resistance of ceramics as well as non-brittle fracture behavior typical for metals and alloys. Similar material properties are required for re-usable, cost-efficient thermal protection systems for re-entry spacecraft or hypersonic vehicles. Oxide-based ceramic matrix composites (CMC) are developed at the Institute of Materials Research and meet these requirements. Outstanding properties of oxide-based CMC are:
