Abstract
The measurement of thermal wave propagating in the cross section of polymer film layers including the interfaces was performed by edge view observation of IR thermographs analyzed by the Fourier- transformed phase image. The phase jumps observed experimentally, indicates the presence of a thermal boundary resistance between each layer. This effect has been modelled by introducing thin surface skins of poor conductors (air, grease) among polymeric layers. The numerical analysis allows estimating the thickness of these skin layers of less than 3μm.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
