The present article aims to study the mechanical and dielectric properties of styrene butadiene rubber (SBR) reinforced with polyester (PE) short-fiber loaded with fast extrusion furnace carbon black (FEF) in increasing quantities. The effect of carbon particle size on the mentioned properties is also reported. From the results obtained in this article and others, it was found that, the tensile strength and Young's modulus of FEF and HAF carbon black increase with the increase of carbon content whereas elongation at break was decreased. The retaining ability of the tensile strength and Young's modulus of the composites loaded with either FEF or HAF carbon black has been increased with the increase of aging time and decreased by increasing carbon content in the vulcanizates. At certain concentration of carbon black in the rubber matrix, there was an abrupt increase in the dielectric permittively o¯' and the dielectric loss o¯". The concentration at which o¯' and ε" shows a sharp increase is in line with the increase of carbon black particle size. The mechanical and dielectric properties for vulcanizates loaded with smaller carbon black particle size are higher than those loaded with larger ones. The dielectric permittivity o¯' has been increased by increasing the temperature whereas the dielectric loss was decreased. The results are discussed and Interpreted. |
