Research and development performed in recent years in the field of UHTC revealed promising properties of these new materials in the field of extreme environments.
Particularly in applications where high thermal loadings are expected these materials offer high potentials of extended performance for various applications.
However, the combination of high thermal loadings together with high mechanical loadings requires a new class of UHTC. By creating UHTCs with fiber reinforcement an improvement of characteristic properties is anticipated.
Research in this very specific area has been initiated and is currently ongoing based on promising ideas.
This class of UHTCMCs is expected to provide extended capabilities wrt higher performance and better design beyond the abilities of current materials for e.g. applications in propulsion, thermal protection systems and hot structures.
The new material is also expected to enlarge significantly the operating temperature range of high temperature components, the thermal shock resistance and will enable new design solutions of those systems with access to new flight regimes.
In addition to this, advanced characteristics with regard to operation in highly corrosive and chemical aggressive environments are anticipated.
Self-healing capability is also an important characteristic and should be considered in the ongoing research.
For thermal protection and hot structures applications the material can provide zero-erosion properties leading to an unchanged vehicle shape and subsequently more stable and predictable aerothermodynamic characteristics .
This talk reviews the status of this technology, identifies expectations, possible applications, and potential advantages from industrial Large System Integrator (LSI) point of view.
