Subsurface defect detection in FRP composites using infrared thermography
This paper demonstrates the use of digital infrared thermography to detect subsurface defects such as debonds and delaminations in Fiber Reinforced Polymer (FRP) bridge decks. Simulated sub-surface debonds and delaminations were inserted between the wearing surface and the underlying FRP deck specimens. The infrared thermography technique was used to detect these embedded subsurface defects. The use of various cooling and heating methods, including solar radiation, was explored. Surface temperature-time curves were established for different types and sizes of subsurface defects. The results show that infrared thermography can be a useful tool for subsurface defect detection in composite bridge decks. Therefore, the technique can be used for several applications such as quality control during pultrusion of new decks (in factories) and during field construction, as well as for long-term monitoring of in-service decks.
