MODELING OF CARBON BLACK FILLED NATURAL RUBBER VULCANTZATES BY THE STANDARD TRIBOELASTTC SOLID

Mathematical modeling of The dynamic behavior of vulcanizates is reviewed with the emphasis on carbon black filled natural rubber (NR). The 3 constant standard triboelastic solid (STS) model and its behavior are described, in general terms and with specific reference to low frequency shear data for a wide range of filled NR vulcanizate. Good general agreement is found between model and experiment for the data obtained al strain amplitudes down to 0.01; there is also acceptably good correlation between carbon black loading and values of STS constants. For previously published data down to very low strain amplitudes (1*10^-4), agreement is much less satisfactory.
