With the increase of the FRP use, the method of detect flaws and evaluate damages in the FRP are being tried variously. The advancement in resolution of the infrared detectors showed the usefulness of the infrared thermographic imaging method as a detection method of flaws. However, the quantitative evaluation of the damage in the FRP is yet difficult. We obtained the temperature rise curve of the specimen surface of the GFRP, which depend on fatigue damage. The purpose of this study is to evaluate the fatigue damage of the glass fiber mat reinforced CP-resin composites by the infrared thermography. For this purpose, two step fatigue tests are carried out. The specimens were damaged by first test, and evaluate the damage of the GFRP by temperature rise with the second test.
