For the first time, the effect of γ-radiation (with doses of 5, 10, 15, and 20 Mrad) on the structure and mechanical characteristics of a polymer composite material based on low-molecular-weight rubbers has been studied. It is shown that an increased radiation dose increases its breaking stress and decreases the breaking strain. The fracture energies are calculated from experimental values of the breaking stress and breaking strain. It is shown that the strength (fracture energy) of samples increases with radiation dose. On irradiation with a dose of 20 Mrad, samples acquired the property of ebonite, which was indicated by a sharp decrease in the breaking strain and an increase in the breaking stress. Based on the study of IR spectra of samples, it is assumed that the change in their mechanical characteristics under the influence of γ-radiation is caused by changes in the structure of the material, i.e., destruction of the carbonyl double bond and an increase in the concentration of other chemical bonds.

首次研究了γ辐射（5、10、15和20 Mrad的剂量）对基于低分子量橡胶的聚合物复合材料的结构和力学性能的影响。结果表明，增加的辐射剂量会增加其断裂应力并降低断裂应变。从断裂应力和断裂应变的实验值计算断裂能。结果表明，样品的强度（断裂能）随辐射剂量的增加而增加。辐照剂量为20 Mrad时，样品获得了硬玉的性质，这表明断裂应变急剧下降，断裂应力增加。在研究样品的红外光谱的基础上，
