Active Infrared Thermography and Shearography applied to non destructive testing of bonded FRP strengthening systems on concrete structures

Résumé

This summary presents two complementary techniques, Shearography and Active Infrared Thermography, used to detect and characterize depth and width of defects (delaminations or adhesive disbonds) that can take place at the interface between the concrete substrate and the bonded FRP used for the reinforcement of concrete structures. Shearography associated to a depressure solicitation on the one hand, and step heating infrared thermography on the other hand are presented. Performances of these methods are demonstrated using data from experimental inspection of specimens containing calibrated defects. Typically, debonded areas were simulated by locally replacing the epoxy resin with non-adherent polytetrafluoroethylene (PTFE) discs at the concrete-to-FRP interface.
