高空核爆炸时,X射线能量占的比重很大,约为总能量的70％。当弹头遇到高空核拦截时,X射线作用到弹头上,在弹头材料中产生热击波。据估计,一枚百万吨级核弹在100公里高空爆炸时,距爆心5公里处单位面积上的X射线能通量约为10~(10)erg/cm~2。这样强的能流作用在弹头壳体上,壳壁材料内产生很大应力。对玻璃钢能产生峰值应力为万巴级的热击波,如此,弹头壳体
High-altitude nuclear explosion, the X-ray energy accounted for a large proportion, about 70% of total energy. When a warhead encounters a high-altitude nuclear interception, X-rays act on the warhead and generate a thermal shock wave in the warhead material. It is estimated that when a million-ton nuclear bomb explodes at an altitude of 100 kilometers, the X-ray flux per unit area 5 kilometers away from the heart of the explosion is about 10 to 10 erg / cm 2. Such a strong energy flow in the warhead shell, the shell wall material has a lot of stress. FRP can produce peak stress for the million-class thermal shock waves, so warhead shell
