Paper Abstract

In this experimental study we present full methodology for investigation and evaluation of high power laser induced damage and its influence on structural integrity of polymer structural sandwich composites (PSSC) samples covered with various colour paint coatings. The work includes in-situ quantitative monitoring of out-of-plane and in-plane displacements and strains by 3D digital image correlation and temperature fields - by thermovision. The experiments are supported by material reflectance studies and post-mortem, microscopic crater investigations. Conclusions concerning influence of structural core and colour coating on PSSC performance, their structural integrity and laser lethality are presented.
