抗X射线辐射复合材料
anti-X-ray composite materials
抗x射线辐射复合材料anti一X一ray compositematerials用于抵抗X射线辐射造成对材料结构的破坏效应的一类复合材料。材料吸收系数是衡量光子和材料作用的能力。它取决于光子能量和材料所含元素的性质。一般讲元素的原子序数越大，吸收系数越大。X射线照射到材料上，则光子与材料的原子发生作用，X射线在物质中迁移时，被物质吸收变成物质的内能，即X射线能量在物质中沉积。同时，X射线能流密度大，释放的时间极短，使材料的比内能急剧增加而升高温度，并且在材料表面处形成很高的压力。结果在材料表面形成一个峰值极高、持续时间极短的压力脉冲一热击波，使材料产生“层裂”效应，同时产生瞬时过载，结构产生变形，乃至破坏。 为了防止X射线的破坏作用，曾提出一种物理模型。它由迎光层、屏蔽层、衰减层和过渡层4层结构组成。衰减层采用泡沫塑料，其他层分别采用碳一酚醛、高硅氧一酚醛等复合材料。利用密度小、质量轻的硅酸盐类多孔复合材料，既可防止大能量的X射线的辐照，同时也是解决能量沉积行为的极好材料。 (于翘)
