Introduction Under mechanical stress, temperature, moisture, radiations, and corrosive and aggressive environments, material performances decrease over the time. e alteration of use properties is named “aging” . Understanding and predicting these degradation processes are really a great challenge. Consequently, the evaluation of material lifetime is very complex; this diculty increases when compositematerials are considered. In this paper, our attention is focused on a specic composite material: orange polymer-based ooring. is ooring is amixture of dierent organic and inorganic llers with an organic orange azoic pigment (C32H24N8O2Cl2) in a polymer matrix. e polymer matrix can correspond to dierent homopolymers or copolymers: natural rubber (NR), styrene butadiene rubber (SBR), or polybutadiene (PB).
