Abstract

This PhD work intends to contribute to the characterization of structural bonded repair quality of primary composite structures using InfraRed Thermography (IRT). Generally, in this case, the parent structure and the repair patch are both made of carbon-epoxy and are linked together by an epoxy adhesive. Such repair configuration then leads to a weak property contrast between the parts of the repaired assembly. Therefore, the non-destructive analysis of the bonding quality remains dificult and represents the very challenging issue of this study. In this way, a new specific Non Destructive Testing (NDT) procedure has been firstly developed that allows physically consistent numerical model of the thermal problem and a good correlation with experimental data. Additionally, it is proposed to use relevant additives that modify the thermal properties of the glue joint in order to improve the detection of bond defects.
