Electrical conductivity of styrene-butadiene rubber/polyester short-fiber reinforced with different types of carbon black

Measurements of electrical conductivity for a composite of styrenebutadiene rubber (SBR) and polyester (PE) short-fiber reinforced with different types of carbon black [high abrasion furnace (HAF) and fast extruding furnace (FEF) black] in increasing quantities have been carried out at different temperatures (30-60degreesC). To find out the effect of the type of carbon black, particle size, and the quantity of carbon black, on the electrical conductivity of the SBR/PE short-fiber composites. It was found that the electrical conductivity increases as the carbon content increases in the composites. Samples loaded with FEF carbon black showed lower conductivity values in comparison with those loaded with HAP carbon black, besides, they possess a reasonable conducting stability as the temperature rises. The results are discussed and interpreted.
