Abstract

The evolvement of guided wave features during the process of composite material degradation is studied. It is shown via experimental data that the amplitude and time of flight (TOF) of waves clearly varies with the degradation of carbon-fiber-reinforced polymers (CFRP) and a significant transition of both features can be observed when delamination appears. The features of amplitude and TOF are then used to estimate the type of damage of CFRP. An improved feature extraction method is proposed. Along with the Gaussian discriminant analysis method, the damage detection accuracy is improved.
