METHOD INTENDED FOR ASSESSING THE DAMAGE TO A PAINT-COVERED COMPOSITE MATERIAL BY MEASURING TWO SEPARATE CRITERIA ON THE SPECTROGRAM |
摘要 |
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. |
