PREDICTION OF THE OXIDATION BEHAVIOUR OF CARBON FIBRE- BASED HIGH TEMPERATURE COMPOSITES FOR HYPERSONIC FLIGHT AND POWER GENERATION

摘要

Hypersonic flight conditions provide a challenging thermal and chemical environment for re-entry from space to earth and for future high speed planes. Efficient thermal protection systems are required to maintain the structural integrity and to keep appropriate internal temperature levels. Hot components for power generation are expected to work in similar, in terms of durability even more challenging high temperature environments beyond the application limits of currently mature technology. Continuous-fibre-reinforced Ceramic Matrix Composites (CFR-CMC) are considered by many the most promising candidate material class to achieve the ambitious goals~1. The use of CMC-based components promises a strong economic and environmental impact. Nevertheless, a number of obstacles has still to be overcome by interdisciplinary R&D to fulfil operation requirements in power generation2.
