An improved penetrator rod for a kinetic energy projectile is disclosed. edded as a central core within said penetrator rod is a lubricating rod, comprising metal alloys such as tin zinc, aluminum, or lead, which will continue to follow as it erodes upon penetration despite the heat and pressures of impact to an armor target. A new, lubricating, front end surface constantly re-appears as the front end of the penetrator erodes upon impact.

Long rod penetrator

An improved fiber reinforced penetrator rod for a kinetic energy projectile aving enhanced penetrating strength is disclosed herein. Embedded in a matrix medium of depleted uranium, or liquid phase sintered tungsten, are long fibers of tungsten-hafnium-carbide which are knitted into a continuous weave over the entire length of the fibers. This prevents splaying open or splitting of the front end of the fibers, and hence of the whole penetrator rod front end, upon impact, penetration, and receiving of the compressive forces upon hitting an armor target.
