ABSTRACT:
Improved shaped charge assembly of relative lightweight and sealable consction and composed of nonmetallic and nonmagnetic materials that can be used for selectively destroying or disarming a variety of targets. The assembly is generally made up of casing means of tubular-like configuration, jet-forming linear means of conical shape and shaped charge body means. The liner means is interposed between the ends of the casing means where the charge body means is interposed between the casing means and the liner means at one end of the casing means. Depending upon the manner in which the assembly is to be used, at least the one end of the casing means is capped. Suitable plastic materials for use in the liner means have been found to be either polyethylene or polypropylene, having an ultra-high molecular weight. Optimum geometric parameters have been found in the use of these plastic materials for limiting the size and angular configuration of the liner means, the depth of the charge body means above the liner means, and the length of the casing means between the liner means and its other end, all for the purpose of assuring that the assembly causes the formation of an efficient jet for penetrating a target. Whenever it is required to boost the explosive effect of the shaped charge assembly, a sleeve of suitable plastic explosive material can be disposed about the one end of the casing means. Since the liner means has a density which is very similar to that of the charge body means, the assembly can form a jet having a front-tip velocity of at least 6,000 meters per second (6 km/s).
