Thermal Conductivity of Reinforced Plastics

Thermal conductivity measurements were made with a Colora Thermoconductometer, which is described in detail by Schrbder [10]. A cylindrical test sample is placed between two silver plates that are maintained at constant temperatures by liquids with different boiling points. Saturated vapor from the liquid with the higher boiling point condenses on the lower silver plate and transfers energy to the sample. The liquid with the lower boiling point evaporates from the upper silver plate, and the generated vapor is condensed and collected in a graduated container.
