Mechanical characterization of carbon black filled NR/BR compounds from small strains up to fracture

As known from the literature (Massie 1993 & Sircar 1973), the NR/BR blend is heterogeneous and exhibits a two-phase morphology. The aim of this work is to compare the mechanical behaviour of the blend with those of its two components. The dynamic-mechanical properties, the tensile behaviour and fracture behaviour of Natural Rubber (NR), Butadiene Rubber (BR) and a 50/50 NR/BR blend, having different Carbon Black (CB) contents, were studied.
