Abstract

The use of composite materials in aircraft industry has risen significantly in recent years. Bonded patch repair technologies provide an alternative to mechanically fastened repairs with significantly higher performance. In this work, the behaviour of scarf-type bonded patches in laminated composites are monitored using full-field measurement methods based on Digital Image Correlation (DIC) techniques which are validated against Lamb wave propagation analysis. The current work focuses on the performance and the on-line monitoring of the adhesively bonded patches in composite plates subjected to tensile loading.
