Abstract:In this study, strain level and temperature-dependent stress relaxation behavior of neat epoxy and graphene-epoxy nanocomposites are experimentally investigated. Tests are performed for neat epoxy, graphene-epoxy nanocomposite with content of 0.1 wt% and 0.5 wt% graphene. To determine the effect of strain levels on relaxation behavior, three constant strain levels are chosen: 3.16%, 7.15%, and 35.5%. Those strain levels are chosen to correspond to different zones on the stress–strain curves as: viscoelastic re… Show more
