This paper has summarized the current status of advanced NDT technology for use in automated defect detection, defect characterization, assessment of concession/disposition and repair strategy for composite production components. A key proposal is the Reference Scan Methodology(Trademark), which makes use of the potential to create or simulate a full-structure full-waveform scan of a 'perfect' component for future comparison of production components. This will enable the rapid automated analysis and sentencing of large-area ultrasonic data captured during the production process in order to filter the scans of acceptable structure and focus the operators on the potentially defective components. Advanced 3D materials characterization methods can then be applied to any defect indications in order to provide accurate information about material properties for the purposes of planning repair strategy or concessions (disposition). The provision of 3D profiles of actual material parameters, rather than NDT parameters such as ultrasonic attenuation or velocity, is a significant breakthrough. The outcome will be a considerable increase in NDT throughput and a more efficient disposition process.
