It will be shown that a consequent modelling of filler‐to‐filler and filler‐to‐matrix contacts and of individual slippage processes allows to describe the mechanical deformation behaviour of rubbers filled with rigid filler particles. The phenomenon of reinforcement turns out to be due to non‐Gaussian rubber elasticity (van der Waals network). Surprisingly, there are universal aspects which characterize the fractal structure in the composite as well as the processes under large strain. Moreover it is possible to deduce the atomic distance distribution in the adhesional layers from WAXS‐measurements. Together with a description of the WAXS‐pattern of pure graphitized and degraphitized carbon blacks some new aspects of the conditions to maximize the filler‐to‐matrix adhesion will be discussed.
