Abstract The interest in composite repair technologies has been recently increased following the wide applications of composite materials in aerospace industry.
In complex structures which consist of multiple layers of different materials and the propagation distances are long, dispersion and multiple modes phenomena might lead to an increase in the duration of the wave’s packet or to a decrease in its amplitude.
Moreover the current work highlights the inefficiency of off-line monitoring techniques for early damage cases in materials where the propagation of damage is highly unexpected such as composites.
