Abstract. The penetration potential of shaped charges is proportional to the
jet length and the square root of the jet density.
The bulk-sound velocities of the liner materials define the maximum
possible jet tip velocities. The jet tip velocities and breakup,
or particulation, times determine the jet length. For shaped-charge optimisations
these parameters have to be considered. After a brief discussion
of these issues, this paper outlines the potential of a
range of materials for use as a possible shaped-charge liner.
It is further noted that, as well as the selection
of optimal materials, a number of other factors have be
taken into account, such as quality of the raw material,
homogeneity, and grain-size distribution. Finally, the paper describes the different
production possibilities for copper liners, identifying the advantages and disadvantages
of each. In particular, the flow-turning process is discussed with
its potential for spin compensation.
