Abstract :
Moisture absorption is a water diffusion process known to alter many of the mechanical properties of polymer-based composites. This study presents ultrasonic characterization of moisture content based on the transmission of acoustic waves through composite plates. The elastic constants of fourteen plates with different controlled water contents are obtained. First the redundancy of the results allows to validate the characterization process and the assumption made on the samples´ symmetry. The sensitivity of the process to moisture content is then discussed
