The ultrasonic immersion technique, using a water coupling medium, is now a standard method for the non-destructive inspection of anisotropic composite materials. Using a goniometer to investigate a composite material in any direction of propagation, their anisotropic elastic l,2 or viscoelastic 3,4 properties can be determined. A comparative analysis of the through-transmission ultrasonic bulk wave methods was recently published by Y.C.Chu and S.I.Rokhlin 5.
