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.

高能电子辐照破坏硅-有机复合材料

研究了加速电子辐照对有机硅复合材料的破坏。实验结果表明，在103 Gy量级的辐照剂量下，硅-有机复合材料的机械强度显着降低，在106-107 Gy量级的辐照剂量下，它们发生完全破坏。使用数学模型从理论上研究了这种现象，该模型用于计算复合材料的机械特性，该模型基于以下观点：复合材料的破坏是由局部缺陷逐渐积累和合并成大块材料中临界尺寸的大簇引起的。由电子流动形成的辐射缺陷是通过固体辐射物理学中开发的方法计算出来的。从缺陷的浓度和分布来看，
