Ultrasonic method detects microstructural damage

摘要

A novel ultrasonic technique for detecting potentially dangerous cracks in aircraft components made of polymer-based composites is being developed in the UK. The technology, which can also be used to detect faults in metallic components, and in non-aerospace structures such as ships and nuclear power plants, is being developed at the Research Centre in Non-destructive Evaluation (RCNDE), based at Imperial College, London, with support from the Engineering and Physical Sciences Research Council (EPSRC), Rolls-Royce plc, Airbus, British Nuclear Fuels Ltd (BNFL) and the UK Defence Science and Technology Laboratory (DSTL).
