Structural integrity assessment of materials by thermography

Thermographic approaches, passive and active, are widely used due to the outstanding advantages that offer in a number of applications and particularly for the assessment of materials. Nonetheless, there are limitations; depending upon the approach used, as well as on the materials thermal, optical and physical properties, proper assessment (detection and/or quantification) is feasible. In this work, different applications, employing thermographic testing, concerning the assessment of various materials are presented. The following applications are included: Through skin sensing development & trials on aircraft materials (Al-2024T3 & CFRP). Assessment of defects under composite patching. Quality assurance and structural evaluation of GRP pipes by using PT. The results of this study show that thermography can be used successfully for the structural integrity assessment of different materials and/or components.
