Mechanical damage characterization of glass fiber-reinforced polymer laminates by ultrasonic maps

Abstract : A method for simultaneous measurement of the thickness and density for Glass Fibre-Reinforced Polymer (GFRP) laminate plates with ultrasonic waves in C-Scan mode is presented in the form of maps. The method uses three different signals in immersion pulse-echo C-Scan mode. The maps obtained based on the density show the heterogeneity of the material at high resolution at the pixel level (1x1 mm2) and therefore they represent an efficient tool to assess and evaluate the damage of the composite structures after manufacturing and after an applied mechanical loading.
