AEA TECHNOLOGY has developed new processing techniques, which it says cut the cost of producing fibre-reinforced ceramics. Fibre-reinforced glass- ceramic composites are suitable for use in turbine-engine components, but, until now, the cost of these materials has been prohibitive.
AEA's System 2 composite has reduced cooling requirements, is lighter than metal and can withstand thermal-shock loading. It is tough and can easily be bolted into position, making it suitable for use in intermediate engine casings, exhaust nozzles and thrust- reverser components, says AEA.
