A study of thermomechanical and thermophysical properties of FPCM Durostone

The paper presents the results of measurements of the thermomechanical and thermal characteristics of the fibrous polymer composite (FPCM) Durostone used in power electronics for manufacturing of support-fixing elements. The coefficient of thermal expansion and thermal diffusivity of the samples were measured in the temperature range from 30 °C to 200 °C. A differential thermal analysis and thermogravimetry were done in the temperature range from 30 °C to 400 °C. When measuring thermal diffusivity by laser flash, a waveguide effect of the FPCM Durostone reinforcing filler was revealed.
