Multi-Pulse Infrared Thermography Applied to Improve Defect Detectability of Composites
Applied Mechanics and Materials, 2011Traditional pulse infrared thermography uses a single pulse with high energy to heat the specimen. For deeper or smaller defects, more energy must be conducted into the specimen to improve the detectability, which also may cause thermal impact damage in particular for composites.

Investigation of honeycomb structure using pulse infrared thermography method
SPIE Proceedings, 2010To reduce weight and improve strength in the aerospace industry, composite structure has gained popularity as a replacement for conventional materials and structures, such as adhesive bonding and honeycomb structure. Honeycomb structures composed by a honeycomb core between two facesheets are very common on aerospace parts.

Thermal characterization of rods, tubes and spheres using pulsed infrared thermography
Journal of Physics D: Applied Physics, 2007In this work we analyse the accuracy of an extension of the flash method to measure the thermal diffusivity of rods, tubes and spheres, which was recently proposed by the authors. We have performed measurements in a wide set of calibrated samples of different sizes and we have found that a lower limiting size of the radius can be established for the ...

Pulsed infrared thermography to inspect the internal defects of composite insulators
2017 IEEE Electrical Insulation Conference (EIC), 2017A non-destructive testing method for internal defects detection is desperately needed due to wide and increasing application of composite insulators in the power grid. In this study, a novel approach based on pulsed infrared thermography was investigated with the aim of testing and evaluating the state of composite insulators.

Journal of Nondestructive Evaluation, 2020
Thanks to its good strength/mass ratio, a glass fibre reinforced plastic (GFRP) composite is a common material widely used in aviation, power production, automotive and other industries. In its turn, active infrared (IR) nondestructive testing (NDT) is a common inspection technique for detecting and characterizing structural defects in GFRP.

Des analyses par thermographie pulsee conduites sur des donnees experimentales et simulees sont presentees. Ces methodes sont appliquees a des donnees issues d'une camera infrarouge non refroidie equipee d'un detecteur matriciel a microbolometres (de moindre sensibilite thermique que les cameras refroidies).

Dynamic infrared multispectral imaging of paintworks by active pulsed thermography
2023Active pulsed thermography method for characterization of complex painting structures and analysis of defects caused by ageing and environmental effects was under study. A painting (26 cm x 32 cm) of XIX century and a replica (46 cm x 55 cm) of Franz Hals (La Bohémienne 1628-1630) were analysed. Following rapid (20 ms duration) flash lamp excitation of

Pulsed infrared thermography processing and defects edge detection using FCA and ACA
Infrared Physics & Technology, 2015Abstract CFRP sheet with delamination defects was detected using pulsed infrared thermography. The principle of polynomial fitting the derivative time algorithm (FDA) and related coefficient algorithm (RCA) was described. A new polynomial fitting the derivative time-related coefficient algorithm (FCA) was formed by combining FDA and RCA, which ...
