An estimation of thermophysical properties of layered materials by the laser-flash method
Wolfgang Hohenauer, Libor Vozár
An investigation of two-layered and three-layered systems by the flash method has been carried out. Because of the behaviour of the material analysed, the theory considers two-layered and three-layered composites with the ideal thermal contact described by zero thermal contact resistance. The data reduction algorithm is introduced and results are given of an estimation of the thermal diffusivity of alumina (aluminium oxide, Al2O3) on copper/alumina layers.
