Over the last few decades there has been an increased adoption of composite materials into engineering systems. This mainly to reduce weight, resulting in lowered energy and fuel consumption. At present, unlike its metallic counterparts, composites materials cannot be recycled effectively. Therefore to stop materials unnecessarily being sent to landfill, it is imperative to repair composite components to extend their service lives. This puts greater importance on the process of evaluating if a composite repair has been accomplished successfully. This paper presents the initial stages in the development of a method using guided acoustic emission to assess the repair, and the computational modelling performed to validate the process.
