ABSTRACT

In this study we investigate the influence of thermal aging on the mechanical properties of a butadiene rubber filled with carbon black. To emphasize the influence of both the crosslink density and the crosslink lengths, we consider three different materials based on the same formulation. Dynamic and quasi-static characterizations are realized periodically at room temperature to study of the impact of aging on various mechanical characteristic such as the equilibrium hysteresis, the Payne effect, etc. Crosslink density is followed by swelling tests.
