Abstract

This study is intended to establish quantitative relationships between impact damage energy and some thermal NDT parameters in application to carbon/carbon composites. When applying uniform optical stimulation, the used approach involves the synthesis of effusivity/diffusivity images respectively in one- and two-sided test procedures. Ultrasonic stimulation of composites has also proven to be attractive due to its special applicability to detect micro-cracks. However, quantitative relationships between temperature signals and impact energy are still to be studied.
