ABSTRACT

This research utilized the Infrared Thermograph, the latest aviation technology for inspection and quality control in Fiber Reinforcement Polymer (FRP). This technology has the capacity to quickly locate any defect present in the FRP composite matrix, as well as to accurately measure the extent of the defect. The experiment employed a parametric study, constructing a concrete slab structure with an FRP bond subjected to thermal analysis in order to determine the optimum values in temperature and distance. Based on the result of the experiment, infrared inspection technology can be used as a non-destructive inspection method and quality control for FRP-reinforced construction. However, the material subjected to FRP technology should be heated evenly and the temperature should be maintained at 5.9 ±2 °C. Moreover, the optimum distance for taking a picture with infrared thermograph is 3 meters to obtain a desirable result.
