Titel
Laser shock waves technique for damage threshold determination of aeronautic composite materials
Abstract
Laser shocks were performed on two aeronautical composite materials. The use of time resolved image acquisition enabled to study the dynamic behavior of the damage induced by the laser shock wave propagations. Since laser loading is really short, post-mortem analysis were possible. X-Ray radiography, cross section micrographies and Interferometric confocal microscopy were used to investigate the laser shock effect on composite material. Main damage dimensions were compared from one material to the other. A difference in the damage threshold to laser shock was lightened.
