Abstract. Effective thermal conductivity and thermal resistance of a plate fragment made of basalt-fiber reinforced composite material are derived from stationary thermal mode measurement data. The experimental setup includes a climate chamber, precision signal converter Tercon, and special thermal flux converters PTP-1B with built-in temperature sensors. Initial data for calculation of thermal conductivity has been obtained with the use of computer code developed in Borland Delphi 7 as a Windows application. High strength reinforced plate is reported to have almost the same effective thermal conductivity as the "classic" thermal insulation materials (glass wool, slag wool) which do not possess the required strength.
Keywords: heat flow converter, thermal conductivity, steady-state thermal condition, basalt-fiber reinforced composite materials, precision signal converter, climate chamber
