Guth-gold式
WebIncreasing the volume fraction of carbon black in natural rubber vulcanisates results in a nonlinear increase in the modulus. This stiffening effect is usually explained in terms of the Guth-Gold type of equation which relates the modulus to the shape factor, occluded volume and the hydrodynamic effects of the filler. WebSep 1, 1973 · The elastic modulus G f ′ of filled SBR vulcanizates has been measured as a function of strain amplitude A.At low loadings of carbon black (20 phr), where G f ′ is practically independent of A, the value of G f ′ (at 25° C, 0.25 Hz) can be predicted within 5 per eent from the gum modulus G g ′ by the Guth—Gold equation with due allowance for …
