| 摘要 |
The invention 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 comprising the following steps: taking (50) from the part a sample of composite material; subjecting (51) the sample to modulated temperature differential calorimetry; determining (52), 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 (53) the thermal ageing of the composite material by comparing the temperature at which the local extremum appears with a reference chart (63). |
