Thermophysical properties of porous mineral-resin composites determined by a transient measurement technique

Abstract

Due to the continuous development of material sciences there is a constant demand to determine the thermophysical properties of new materials especially in the field of polymer technology. The temperature dependent volumetric heat capacity and thermal conductivity of two different porous mineral-resin composites were measured simultaneously by a transient technique developed by the authors. The technique includes one transient measurement and a genetic algorithm based evaluation method. We shortly present the principle of the technique and the measurement process and results for the two materials. The applied measurement technique can reduce the time consumption and the costs of the measurements compared to other well-known methods.
