Abstract

Ultrasonic non-destructive testing of carbon fiber composite (CFC) aircraft panels has, in the past, been a time-consuming and laborious process. Data acquisition (using C-scan techniques) takes of order 1 hour per m², and the decision as to whether the panel meets the testing standard (technically known as sentencing) is an unexciting and repetitive visual task for a human operator. This paper introduces a new system for automated sentencing of CFC panels of solid or matrix (honeycomb) construction. It begins with a brief description of a new parallel-scanning ultrasound rig which greatly reduces the time required for data acquisition. A detailed description is then given of the design and implementation of a computer vision system which processes the resulting ultrasound images.
