Abstract:
A non-destructive method for determining an amount of temperature exposure to a Bismaleimide Resin (BMI) matrix substrate, the method includes determining component data of a Bismaleimide Resin (BMI) matrix component via fourier transform infrared (FTIR) spectroscopy; correlating the component data to model data to determine a structural debit from temperature exposure; and bounding a structurally damaged area in response to the correlating.
