AbstractWe are presenting the developments at the National Research Council of Canada of 3 laser-based inspection techniques for polymer-based composites. Laser-ultrasonics probes the material with ultrasound and useful for detecting delaminations, disbond in bonded assemblies and porosity. Laser tapping senses the vibrations induced by laser excitation and is useful detecting detachment and other defects in honeycomb and foam core structures. Laser shockwave testing is a non invasive proof test for adhesive bonds and provides an evaluation of bond strength.
