- Abstract
- The method of laser-ultrasonic defectoscopy which allows to determine porosity levels of polymer composite materials is presented. In the example of carbon fiber reinforced plastic samples and stringer panel is shown that such materials characterize by a significant variation of local porosity. Comparison of results obtained by methods of laser-ultrasonic defectoscopy and X-ray tomography is given.
