Experimental data on mechanical behavior of polymer composite material on the postcritical deformation stage were presented. The typical dependences effect of deformation rate and temperature in a wide range (high and low) on the regularities of deformation and the realization degree of postcritical deformation stage on tensile test were obtained. The tests were carried out on the specimens of constructional glass-reinforced plastic with various lay-up sequences. Test runs were carried out at different loading rates (between 0.1 and 10 mm/min); in a wide temperature range (betwen - 40°C and 200°C) and with different stiffness. The loading conditions are determined under which the degree of implementation of the postcritical stage of deformation increases.
