The quality and variety of their properties, the composite materials are widely used in naval military. The possibility of integrating smart function in materials represents a significant advance for their uses. To reduce the costs of inspections required, it is preferable to use materials integrating a health monitoring. Thus, we sought to define a nondestructive evaluation method, to provide better security at lower cos structures. The Lamb waves were seen in their work this concept is generalized to the case of anisotropic laminated materials. The characteristics of these dispersive modes have been studied in relation to mechanical properties. Achieving instrumented plates allowed the detection of realistic defects by defining damage parameters. The location of defects was estimated by a signal processing based on discrete and continuous wavelet transform. Finally, the Lamb modes were modeled using the finite element method. In parallel, an electromagnetic shielding based on the electrical conductivity of carbon fibers have allowed us to obtain a high level of shielding effectiveness for the military naval sector. In particular, the importance of electrical continuity between the different plates on the measured performance was developed. A model based on the distributed point source method allowed us to model the propagation of electromagnetic waves. The originality of this study is the integration of two functions in composite materials.
