Summary on Grant Application Form |
|
The research will investigate the design and properties of a new ultrasonic transducer system for the detection of defects in engineering composites. The areas of specific interest are the detection of delaminations in carbon fibre composites (eg aircraft wings) and the monitoring of damage around bolted joints of civil engineering structures made from pultruded glass fibre composites. The work will use a new gas-jet approach to couple the ultrasonic energy to the composite sample, where the gas (eg carbon dioxide or helium) within the jet has different acoustic properties to air. The result is an acoustic waveguide, shielding the ultrasound from external atmospheric conditions which would lead to unwanted scattering and attenuation of ultrasound. The approach would then allow gas-coupled ultrasonic scans to be performed outdoors, in either through-transmission or in pulse-echo mode.
