The stress diagram of polymer composite material based on PDI-3A rubber filled with thermally expanded graphite or potassium chloride before and after microwave treatment for 300, 600, 900 and 1200 s has been studied. A twofold increase in tensile strength and deformability was found after microwave treatment for 300 c and testing at 223 K. With increasing the test temperature or microwave treatment time, a marked decrease in the deformation and tensile strength characteristics of the obtained composites was observed.
