In this paper, a method for the characterisation of orthotropic, plate-shaped material samples is presented. Ultrasonic plate waves are excited at different angles and then detected. Then, a two-dimensional simulation model can be used to inversely estimate a set of material parameters for each angle of propagation. After merging these individual results into a global set of parameters, the material’s elastic behaviour can be described for arbitrary load directions. The procedure is exemplarily applied to characterise continuous-fibre reinforced polymers.
