The influence of repressing liners made from sintered copper on jet formation

The results of the investigations of the shaped charges with liners made finally by repressing of sintered copper are presented in this work. The influence of the repressing conditions of the liners, i.e. their strain deformation, on jets formation were estimated. The main characteristics of the jets, i.e. tip velocity, break up time and ideal depths of the target penetration for different strain deformation of the liners, i.e. 6.6, 14 and 25%, was determined. The liners with value of the strain deformation 6.6% had the best parameters of the jets.
