Thermographic inspection of bond quality of FRP strengthened concrete
The bond quality is critical to stress transfer between fiber reinforced polymer, FRP, and concrete structures. The efficacy of externally bonded FRP systems could be reduced significantly due to defects at the FRP-concrete interface. Infrared thermography is an effective tool for locating such defects in a non-contact fashion. Current study examined the effects of size and depth of interface defects on surface temperature contrast. The sequence of defects appearing in a thermal image was determined by heat input and size and depth of defects collectively. Further analyses on the quantitative inspection are underway. Results of signal processing and image reconstruction will be presented.
