The present invention is an improved penetrator. This penetrator, which is composed of tungsten, has superior, sought after properties. It may be produced by employing metal matrix composite technology. The tungsten penetrator herein differs from tungsten penetrators in the prior art in that it is composed of tungsten whiskers. Although different crystalline orientations of tungsten whiskers may be employed within the scope of the present invention, the orientation is the one preferred.

 

Tungsten penetrators already in use (i.e., those in the polycrystalline form) tend to form mushroom heads upon impact of a hard target. The formation of a mushroom head decreases the penetration ability of a penetrator. Hence, the performance of a penetrator would be enhanced if the formation of a mushroom head could be eliminated. The penetrator of the present invention is designed to prevent the formation of a mushroom head during its penetration of armor materials or other hard materials--i.e. steel.

 

Although penetrators do exist which do not form a mushroom head upon impact, these penetrators carry with them other undesirable properties. For example, the most effective penetrators to date are those composed of uranium. Even though uranium based penetrators do not form mushroom heads upon impact, their radioactive nature makes them undesirable in that additional considerations need to be addressed in their use--i.e. the disposal of radioactive waste, etc.

 

Accordingly, it is an object of the invention to provide a penetrator having superior penetration ability and strength.

 

It is another object of the present invention to provide a penetrator having superior penetration ability and strength which is not radioactive in nature.

 

It is another object of the invention to provide a tungsten penetrator having superior penetration ability and strength.

 

It is a further object of the invention to produce a penetrator which employs tungsten whiskers therein.

 

It is still a further object of the present invention to produce a penetrator which employs tungsten whiskers therein, wherein said tungsten whiskers are of the orientation.

 

Still a further object of the invention is to provide a tungsten penetrator which will not form a mushroom head upon impact of targets.
