Abstract
A shaped charge apparatus having an improved liner for a shaped charge constructed from a combination of powdered metal and selected polymer material. Powdered heavy metal and polymer binder is compressively formed into a rigid shaped charge liner under very high pressure. The polymer binder may be in powdered form and or also be used to coat the powdered metal particles prior to compression. The compressed liner may also contain a relatively small percentage of other material to enhance lubrication or corrosion resistance.
