Geometrical Limitations to Detection of Defects in Composites by Means of Infrared Thermography
Source abstract
Abstract
The aim of the present experimental study is to gain information about limits in detection of defects in composites by infraredthermography. Specimens are manufactured of either carbon/epoxy, or glass/epoxy, and withinclusions of foreign materials to simulate defects of different size and positioned at different depths. Tests are carried out by using both pulse and lockin techniques. Results are presented in terms of difference of temperature (pulse), or difference of phase angle (lockin), between damaged zones and sound material. It seems that, apart from diameter and depth, thethickness is very crucial for defects visibility.
