Study of an optimal heating duration indicator for square pulsed thermography applied to CFRP gluing quality control

Infrared Thermography in Civil Engineering: From non Destructive Testing in Laboratory to Outdoor Thermal Monitoring

“…To introduce transfer from laboratory conditions to real field, we will lean on some laboratory works on active thermography applied to quality control of reinforcement operations by gluing composite (CFRP) plates or tissues on concrete structure [4] or voids in pavement [5]. First, we will introduce and discuss the benefit of using numerical heat transfer modeling to optimize the control process [6,7] or generate virtual thermal image sequences to test post-processing methods [8_,9]. It will be followed by presentation and discussion on experiments carried out using laboratory specimen.…”
