The destruction of silicone composites irradiated by accelerated electrons is investigated. Experimental results showed that, at irradiation doses of the order of 103 Gy, the mechanical strength of silicon—organic composites is significantly reduced, and doses of the order of 106–107 Gy, their total destruction occurs. This phenomenon was investigated theoretically using a mathematical model for calculating the mechanical characteristics of composites that is based on the idea that their destruction is caused by a gradual accumulation and merging of local defects into large clusters of critical sizes in the bulk of the material. The radiation defects formed by the flow of electrons were calculated by methods developed in the radiation physics of solids. From the concentration and distribution of the defects, the average mechanical characteristics of the composites were determined.
