Excitation of acoustic emission by laser radiation for studies of structural alterations in composites and polymers
Source abstract
Abstract
The special features of excitation of acoustic emission (AE) by laser radiation are studied. It has been found that ruby and copper-vapor lasers reliably excite AE with an amplitude high enough to be detected. It has been shown that AE parameters of polymers have a significant sensitivity to the type of laser irradiation used for initiating local thermal destruction. The results can be used for remote acoustic calibration and initiation of local thermal destruction during AE diagnostics of thermal stability of polymers and composite materials.
