We study the impact of the inherent anisoptropy of carbon black (CB) aggregates on the behaviour of sheared suspensions containing CB that serve as a precursor to conductive composite materials.

We propose a simple percolation criterion for arbitrary percolation problems that provides the exact percolation thresholds for a large number of exactly solved percolation problems as well as specific continuum percolation problems.
