Abstract: The utilisation of fibre-reinforced metal, intermetallic and ceramic matrix composites (CMCs) in gas turbine engines offers the potential of improved fuel efficiency, higher operating temperature and greater thrust to weight ratio. The development of ceramic fibres with high strength, excellent strength retention at elevated temperatures and good creep resistance is essential to the successful implementation of composites in various high temperature components. Several single crystal oxide and oxide/oxide eutectic fibres have been developed to meet the demanding performance requirements. Recent progress made on developing these fibers will be discussed.

Keywords: directional solidification; single crystal oxide fibre; oxide/oxide eutectic fibre; lamellar microstructure; coarsening; gas turbines; high temperature components; ceramic fibres.
