  • Method of characterizing the thermal ageing of composite materials, in particular composite materials having an organic matrix
    Patent number: 9995699
    Abstract: The present disclosure relates to a method of characterizing the thermal ageing of a part made of composite material, in particular a composite material having an organic matrix. The method includes taking from the part a sample of composite material, subjecting the sample to modulated temperature differential calorimetry, determining, from the curve representing the total heat flow component associated with irreversible phenomena, the temperature at which a local extremum appears, this local extremum being characteristic of the thermal ageing, and determining the thermal ageing of the composite material by comparing the temperature at which the local extremum appears with a reference chart.
    Type: Grant
