Autonomous inspection and repair of aircraft composite structures

Kostopoulos, Vassilis; Psarras, Spyridon; Loutas, Theodoros; Sotiriadis, George; Gray, Iain; Padiyar M, Janardhan; Petrunin, Ivan; Raposo Gaudencio Campos, Joao; Zanotti Fragonara, Luca; Tzitzilonis, Vasileios; Dassios, Konstantinos; Exarchos, Dimitrios; Andrikopoulos, George; Nikolakopoulos, George (Elsevier, 2018-11-23)

This paper deals with the development of an innovative approach for inspection and repair of damage in aeronautical composites that took place in the first two years of the H2020 CompInnova project which. The aim is a newly ...
Fast, accurate, and reliable detection of damage in aircraft composites by advanced synergistic infrared thermography and phased array techniques

Padiyar M, Janardhan; Fragonara, Luca Zanotti; Petrunin, Ivan; Raposo, João; Tsourdos, Antonios; Gray, Iain; Farmaki, Spyridoyla; Exarchos, Dimitrios; Matikas, Theodore E.; Dassios, Konstantinos G. (MDPI, 2021-03-19)

This paper presents an advanced methodology for the detection of damage in aircraft composite materials based on the sensor fusion of two image-based non-destructive evaluation techniques. Both of the techniques, phased-array ...
Improving depth resolution of ultrasonic phased array imaging to inspect aerospace composite structures

Mohammadkhani, Reza; Fragonara, Luca Zanotti; Padiyar M, Janardhan; Petrunin, Ivan; Raposo, João; Tsourdos, Antonios; Gray, Iain (MDPI, 2020-02-20)

In this paper, we present challenges and achievements in development and use of a compact ultrasonic Phased Array (PA) module with signal processing and imaging technology for autonomous non-destructive evaluation of ...
Lamb wave-based air-coupled ultrasonic inspection technique for filament-wound composite pipes

Padiyar M, Janardhan; Balasubramaniam, K. (British Institute of Non-destructive Testing, 2014-04-01)

Filament-wound glass epoxy composite pipe-like structures require ultrasonic inspection in order to characterise any potential defects, such as those due to foreign inclusions and delaminations, so that defective as-manufactured ...
Quantitative characterization of interface delamination in composite T-joint using couplant-free Lamb wave methods

Padiyar M, Janardhan; Balasubramaniam, Krishnan (Sage, 2015-11-24)

Research in quick Non-Destructive Evaluation methods for field maintenance of aircraft has become a focus of attention due to increase in the use of co-cured skin-stiffened composite structures. When Lamb wave propagates ...
