In Search of Early Time: An Original Approach in the Thermographic Identification of Thermophysical Properties and Defects

Figure 6

Normalized experimental pulse diffusivity rear face thermograms (mean temperature) obtained with a series of 3D C/C coupons of different thicknesses. Comparison to the homogeneous medium solution with the identified homogenized diffusivity, , and to the 1D directional reinforcement composite equivalent to the 3D C/C using the identified parameters: axial thermal diffusivity of the reinforcement, , diffusivity of the matrix, , and thermal contact resistance of the reinforcement/matrix interface, . Taken from [10, 13].
