Abstract :
This paper presents a study the possibilities of evaluation of thermal parameters for single and multilayer structures using dynamic thermography. Potentialities of both lock-in and pulse thermography are discussed. Simulation for periodic excitation and multilayer composite material is presented. Practically, the described methods can be used in various applications, eg. microelectronic multilayer components nonwovens manufactured from hemp fibers, chemical fibers and with an addition of electrically conducting fibers, and in medicine and biology.
