Anticipate and characterize damages in layered carbon fiber-reinforced polymers (CFRP) is a challenging problem. Non-destructive evaluation using ultrasonic signals is a well-established method to obtain physically relevant parameters to characterize damages in isotropic homogeneous materials. However, due to their structural complexity, composites require special care in signal interpretation. Some enhancements on the inversion and interpretation are proposed by adapting classical signaldoi:10.1016/j.proeng.2011.07.020 fatcat:whenw7mwrnbxrfcf3jdcskz6za
