The Porosity of Liner Effect on the Shaped Charge Jet Penetration
Shocking temperature rise of the shaped charge with porous liner before collapse was calculated based on the Herrman equation of state. Shaped charges with 36mm charge diameter were used to fire at the 603 armor steel target, the penetration-standoff curves(P-S) of the shaped charge liner with 88.6% and 90.3%T.D were measured and compared. It is shown that proper porosity is helpful to lengthen the jet break up time and penetration depth，which is of significance for the application of porous liner.
