| Abstract: | 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/cm3 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. |

| Keywords: | porous phenolic material spallation characteristic free surface velocity Hugoniot curve |
