Thermal characteristics of filled silicone rubber under laser heating

This work represents the continuation of the work presented by Meyer et al. (IEEE CEIDP, p.848-52, 2002), where thermal conductivity of room temperature vulcanized samples was tested. The thermal behavior of hot pressed silicone rubber filled at 30% and 50% concentrations with alumina trihydrate (ATH) and silica is now explored. A near-infrared laser and a thermovision camera were used to calculate thermal conductivities based on a thermal transient model. In addition to thermal conductivity results, the measurement of temperature in a modified inclined plane test highlights the importance of the thermal conductivity on tracking and erosion resistance.
