The measuring method of thermal diffusivities by using the stepwise light heating method on anisotropic materials and the finite difference method has been developed in order to determine the thermal diffusivity of 2nd-order tensor even when the principal axes are unknown. The experiments were conducted with the carbon / carbon composite (C/C) samples at room temperature. The temperatures measured by infrared sensing devices were weighed against the approximate values of the three dimensional finite difference methods. The results of tests and analyses showed that the tendency of temperature rises on experiments were correspond with the orthogonal anisotropic characteristic of the samples. The experimental apparatus are supposed to need improvement to raise the precision of them because the results had margins of error that can be caused by them.
