Abstract
Abstract This invention relates to shaped charge liners and methods of their manfuacture for use in shaped charge explosives and munitions as used in military, industrial and rescue operations. In a more specific aspect the invention relates to an improvement in shaped charge liners employing spirally wound wire or rod to form the desired geometrical shape of the liner. In this invention, shaped charge liners of a desired shape are fabricated by sequentially winding wire or rod about a preformed mandrel, with the wire or rod being held in proper position through the use of adhesives or solders.
