Summary Sulphur‐crosslinked styrene–butadiene vulcanizate filled with carbon black up to 50 parts per hundred rubber (phr) were mainly investigating using an instrumented impact tensile tester. The experimentally determined and the calculated critical J‐values are in a good agreement. The pronounced energy dissipation capability of the vulcanizate with 50 phr carbon black does not take effect because the existence of a large number of agglomerates seen by using of a transmission electron microscope at reaching the percolation threshold leads to a more brittle behaviour.
