Abstract

The influence of cyclic loading on the residual mechanical properties of the polymer composite was studied. Three-stage diagrams of Young’s modulus reduction, two-stage and three-stage diagrams of tensile strength reduction were experimentally obtained. A previously proposed phenomenological model was successfully applied for describing experimental data. The dependence of the fracture type after static tension on number of preliminary loading cycles was analyzed.
