摘　　要：在利用一级轻气炮加载技术的基础上,确定了一种多孔酚醛材料在一定的冲击速度下的自由面粒子速度时程曲线,并通过对实验数据和得到的曲线分析研究了密度为0.71g/cm3的多孔酚醛样品的层裂特性,得到了其在不同冲击速度下的层裂强度和层裂厚度;通过对该材料自由面时程曲线的分析得到了其D-up型Hugoniot冲击绝热曲线.Free surface velocity for the spallation event of one porous phenolic material was obtained based on the loading technology of the light gas gun. At the same time, by analyzing the experimental data and curves the spallation characteristics of this phenolic material with a density of 0.71 g/cm^3 were studied and the strength and thickness of the spallation were obtained. The D-up type Hugoniot curve of this material was acquired by analyzing the free surface velocity.
