“…The experimental results, achieved with a FPA SBF125 IR camera (Santa Barbara, Lowell MA, USA) and two photographic flash lamps (FX60, Glamox, Borehamwood, UK) powered at 6.4 kJ, showed an increase in the SNR for 96% of defects after processing the images with the PLST technique. Zhao et al [ 52 ] used the Coefficient Clustering Analysis (CSA) method coupled to PT, whilst Chang et al [ 49 ] employed the Multi-dimensional Ensemble Empirical Decomposition (MEEMD) algorithm to quantify material damage in impacted CFRP composites. Pawar and Vavilov [ 48 ] used a 3D Normalisation Algorithm (3DNA) for PT to compensate the background non-uniformity in both damaged glass and carbon fibre reinforced composites.…”

Active infrared thermography is a fast and accurate non-destructive evaluation technique that is of particular relevance to the aerospace industry for the inspection of aircraft and helicopters’ primary and secondary structures, aero-engine parts, spacecraft components and its subsystems. This review provides an exhaustive summary of most recent active thermographic methods used for aerospace applications according to their physical principle and thermal excitation sources. Besides traditional optically stimulated thermography, which uses external optical radiation such as flashes, heaters and laser systems, novel hybrid thermographic techniques are also investigated. These include ultrasonic stimulated thermography, which uses ultrasonic waves and the local damage resonance effect to enhance the reliability and sensitivity to micro-cracks, eddy current stimulated thermography, which uses cost-effective eddy current excitation to generate induction heating, and microwave thermography, which uses electromagnetic radiation at the microwave frequency bands to provide rapid detection of cracks and delamination. All these techniques are here analysed and numerous examples are provided for different damage scenarios and aerospace components in order to identify the strength and limitations of each thermographic technique. Moreover, alternative strategies to current external thermal excitation sources, here named as material-based thermography methods, are examined in this paper. These novel thermographic techniques rely on thermoresistive internal heating and offer a fast, low power, accurate and reliable assessment of damage in aerospace composites.

“…To quantify the material damages in carbon fibre reinforced polymers (CFRP) under impact, Chang el al. [36] used the Multi-Dimensional Ensemble Empirical Decomposition (MEEMD) algorithm. Also for CFRP subjected to impact test, the Coefficient Clustering Analysis (CSA) method integrated with PT was applied [37].…”

Diagnosis and prognosis of failures for aircrafts’ integrity are some of the most important regular functionalities in complex and safety-critical aircraft structures. Further, development of failure diagnostic tools such as Non-Destructive Testing (NDT) techniques, in particular, for aircraft composite materials, has been seen as a subject of intensive research over the last decades. The need for diagnostic and prognostic tools for composite materials in aircraft applications rises and draws increasing attention. Yet, there is still an ongoing need for developing new failure diagnostic tools to respond to the rapid industrial development and complex machine design. Such tools will ease the early detection and isolation of developing defects and the prediction of damages propagation; thus allowing for early implementation of preventive maintenance and serve as a countermeasure to the potential of catastrophic failure. In this paper, following a short introductory summary and definitions, this paper provides a brief literature review of recent research on failure diagnosis of composite materials with an emphasis on the use of NDT techniques in aerospace industry. In addition to this, within a some of significant NDT application extents, prognosis of composites is also briefly discussed.

“…4, it can be seen that even if after subtracting background thermal image, serious noise interference still exists, and the defects shows relatively vague. In order to further improve the contrast between defective and sound areas, Fourier transform of the image sequence has been done [9][10][11][12]. The best amplitude and phase diagrams after Fourier transform were shown as fig.…”

Thermal barrier coating structure components are prone to coating cracking, debonding and peeling defects in the service process, which affects the work safety and reliability of the hot end parts, even result to catastrophic consequences. Experimental research on Yttria-stabilized zirconia thermal barrier coating structure debonding defect detection has been conducted using long-pulsed excitation of infrared wave non-destructive testing technology. Differences between surface temperature signals of sound and defective regions, detection effect comparison of heating and cooling process, detection effect comparison of different defect preparation methods, and impact of inspection parameters on detection effect were studied and discussed. The research conclusions will provide technical guidance to Yttria-stabilized zirconia thermal barrier coating structure debonding defects using long-pulsed excitation of infrared wave non-destructive testing technology.
