A satisfactory account of reinforcement of rubber through the application of the theory of elasticity for its vulcanizates with carbon black fillers has been obtained. A statistical theory of reinforcement by carbon black fillers and its characterization was developed. Three methods for characterizing the reinforcement of carbon blacks by the differences of elastic free energy, retractive forces and modulus were derived from this theory. The influence of carbon black fillers on the mechanical properties of SBR and NR vulcanizates was studied by uniaxial, equi-biaxial and unequi-biaxial extensions. These results show a satisfactory agreement between the theory and experiments. A correlation between the structure parameters of C_(ijk) and the tensile strength for SBR vulcanizates filled by different grades of carbon blacks was obtained.
