Abstract
A thermographic technique for detecting disbonds and delaminations in concrete beams reinforced with bonded sheets of unidirectional carbon fiber reinforced plastic is described. Concrete slab test specimens are fabricated with seeded flaws of various thickness and depth from the surface. The specimens are briefly heated with a projector heat source and infrared images are captured. Digital image processing techniques are applied in order to improve image quality. Flaws are identified. Advantages and limitations of this method are discussed.
