Visualization of Thermal Transport Behavior of Silicone Polymers with Thermally Conductive Fillers

Abstract

Thermal transport properties of silicone polymers containing thermally conductive fillers have been investigated experimentally and analytically. Composite sheets were fabricated by mixing silicone polymer with alumina particles with mean diameter of around 500μm. Temperature distribution observation were carried out with the composite sheets using a thermo-microscope and the effect of heating condition (continuous and pulse heating) on the temperature distribution in the composite sheets was discussed. Additionally, the steady and transient state thermal problems for the random unit cell model of the composite sheet were solved using ANSYS finite element program and temperature distributions in the composite were evaluated.
