Abstract:

Free surface velocity of the carbon phenolic material is obtained based on the symmetrical loading technology of one-stage light gas gun.The high-pressure state properties of carbon phenolic material under high speed symmetrical loading are then discussed；at the same time,Hugoniot curve and Griineisen state equation for the carbon phenolic material are established.The experiment results show that Griineisen coefficients is negatively sensitive with improvement of the particle velocity.

Key words: carbon phenolic material, symmetrical loading technology, physical characteristics
