Fibre reinforced polymer composites offer lightweight solutions, but are currently not used efficiently due to inherent defects resulting from the manufacturing process. Research at the University of Southampton has focused on developing intelligent NDE systems that show how the defect influences structural performance by utilising imaging techniques that measure strain.

In traditional NDE approaches such as ultrasound and thermography only the size and position of the defect are provided. The barrier to applying the imaging based techniques in service, for example on-board ships or on aircraft, is that to make a measurement it is necessary to impart a load so until now the techniques have been confined to the laboratory test environment. In 2012 a team lead by Professor Janice Dulieu-Barton was awarded £1M through a MATERA+ EU Action to develop an imaging system that could be used in service or at the production stage. Dr Richard Fruehmann developed the initial system which is based on imparting a vibrational load that can be developed without a test machine. (Richard received his PhD from the University of Southampton in 2009.) Continue reading A new approach to non-destructive evaluation (NDE) of structures
