Abstract:
A method for assessing damage to a composite material covered with a polyurethane-type paint is provided. Two separate criteria are measured on a spectrogram obtained by infrared spectrometry, thereby characterizing thermal ageing of the paint, each separate criteria being a measurement on a curve of a spectrum of the spectrogram of a height of a particular peak, thereby giving two independent assessments of the thermal ageing. Then, the two separate criteria are combined together in order to obtain a result of a level of the damage.
Abstract:
The disclosure relates to a device for non-destructive testing of a composite part that includes at least two magnetic bodies, at least one of said at least two magnetic bodies being adapted such as to exercise a force of attraction such as to allow mutual restraint, or restraint of one by the other, of the magnetic bodies on either side of said part, said magnetic bodies being intended to be positioned directly on at least one wall of the part to be tested; and at least one transmitting ultrasound probe positioned on one of said magnetic bodies, and at least one receiving ultrasound probe positioned on the other one of said magnetic bodies.
