Application of Nondestructive Testing for Defect Characterization of Concrete Structures Strengthened with FRP
Fiber-reinforced polymer (FRP) composites are being used widely to retrofit civil engineering structures. The success of this kind of systems in performing their intended functions depends, to a large extent, on how well they are bonded to interior and to the external substrates during all their service lifetime. Hence, for the purpose of research and practice, there are needs for efficient and reliable methods to detect and characterize defects at the substrate interface and within multi-ply systems of FRP. According to recent investigations, the debonding of the interface between FRP and concrete, debonding of matrix and fibers, matrix cracking, delamination, and fiber fractures are the main challenge in using strengthening FRP civil engineering field. A review of three useful nondestructive testing (NDT) methods (Radiography, Ultrasonic and Thermography) is given to reveal their advantages and disadvantages in detecting those failures.
