  • Method for assessing the damage to a paint-covered composite material, measuring two separate criteria on the spectrogram
    Patent number: 9797829
    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.
    Type: Grant
    Filed: April 14, 2016
    Date of Patent: October 24, 2017
    Assignee: AIRCELLE
    Inventors: Andre Baillard, Odile Lefeu, Frederic Joubert, Emmanuel Piel

  • Method for the non-destructive inspection of an organic-matrix composite material
    Patent number: 9274002
    Abstract: A method for the non-destructive inspection of a part made from an organic-matrix composite material (CMO) includes the steps of: a) carrying out a surface inspection of the part by Fourier transform infrared spectroscopy (FTIS), b) if step a) reveals a defect, carrying out in-depth inspections of the organic-matrix composite material according to two complementary ultrasound techniques.
