Abstract | A method based on shock waves produced by a pulsed laser is applied to the evaluation of bond strength of composite plates joined by an adhesive layer. A laser shock wave can cause a delamination when it propagates through the adhesive/plate interface. Different laser pulse energies can be used to evaluate this adhesion strength. A good bond will be unaffected by a certain level of shock wave stress whereas a weaker one will be damaged. The method is made quantitative and in-situ by optically measuring the sample surface velocity with an interferometer. The signals give a signature of well-bonded and disbonded interfaces, and are used to obtain an estimate of the bond strength. Results show that the proposed test is able to differentiate bond quality. Also, laserultrasonic measurements made on shocked samples confirmed that weak bonds are revealed by the laser shock wave method. |
