Mechanical properties of polymer nanocomposites based on styrene butadiene rubber with different types of fillers

Аннотация

This article examines the theoretical description of the mechanical behavior of elastomeric nanocomposites based on butadiene styrene polymer, and several species with different filler volume fraction in 30phr and 50phr. To construct the determining equations we use the scheme, whose points are connected by elastic, viscous, plastic and transmission elements. To describe the properties of each element used well-known equations of nonlinear elasticity theory, the theory of nonlinear viscous fluids, the theory of plastic flow of material in the finite deformation of the medium. To obtain the constants of the model used stepwise algorithm. Used in the experiments (cyclic loading, relaxation and creep) can get more information about the viscoelastic properties of rubber.
