In the present work, a new procedure is presented to measure the crack density via thermography in quasi-isotropic CFRP made by an innovative industrial process: Automated Fiber Placement. rnThe measured crack densities during constant amplitude fatigue tests were compared with the Ogin analytical model. rnThe thermal parameter adopted was the second amplitude harmonic of the temperature signal.rn
