Abstract: Rubber carbon black (CB)/rubbery epoxy (RE) and CB/silicone composites with different types, loadings, and silane functionalization of carbon black were prepared. These composites were investigated for their electrical conductivities, and their mechanical properties. The thermal conductivity of each composite was also determined using a Hot Disk thermal constants analyzer. It was determined that the incorporation of carbon black into the composites increased the thermal conductivity in all of the samples. Some of the samples were found to be electrically conductive, while others were electrically insulating depending on the type and loading of the carbon black. The CB/RE composites were found to have improved compression and hardness properties in comparison to a pure RE sample.
