Considering the huge functionality of composite patches in repairing an‎d reinforcing structures especially aeronautical structures, presenting an effective quality control method sounds crucial. Thermographic methods are reliable an‎d fast approaches to investigate composites. In this work, detecting defects of composite patches has been done using vibro-thermography. Desired defects are of type disbond an‎d delamination in composite patch. First using finite element simulation, the vibro-thermography test has been modeled on composite patch. Then, detecting defects an‎d accuracy of estimating these defects have been investigated. The results signify that vibro-thermography is more efficient in diagnosing defects of the depth of composite patch toward the surface defects. Opposingly, pulse thermography detects surface defects better than deep defects.
