Abstract

A preferred projectile includes a toughened polymer resin comprising an elastomer-modified epoxy functional adduct formed by the reaction of a bisphenol A liquid epoxy resin and a carboxyl terminated butadiene-acrylonitrile elastomer; and a curative agent by which the toughened polymer resin is cured; wherein the cured toughened polymer resin is in the shape of a bullet. The projectile preferably has an average density less than the density of lead. A preferred ammunition cartridge includes a propellant and the aforesaid projectile fixed in position relative to the propellant; and an ammunition cartridge includes a primer; a propellant; and the aforesaid projectile; as well as a casing containing the primer, propellant and projectile, with the projectile projecting from the casing.

Claims

1-10. -10. (canceled)

11. A projectile comprising:

a toughened polymer resin;

a curative agent by which the toughened polymer resin is cured; and

a particulate filler distributed through the toughened polymer resin, the particulate filler having a density greater than a density of the toughened polymer resin;

wherein the cured toughened polymer resin is 20 to 30 percent by weight of the total projectile composition.

12. The projectile of claim 11, wherein the projectile has an average density that is less than the density of lead.

13. The projectile of claim 11, wherein the projectile has an average density that is less than 45 percent of the density of lead.

14. The projectile of claim 11, wherein the particulate filler is 70 to 80 percent by weight of the total projectile composition.

15. The projectile of claim 11, wherein the particulate filler includes copper.

16. The projectile of claim 11, wherein the projectile is substantially lead-free.

17. The projectile of claim 11, wherein the particulate filler includes a material selected from the group consisting of copper, tungsten, lead, iron and steel.

18. A cartridge including a casing and the projectile of claim 11, with the projectile projecting from an end of the casing.

19. The cartridge of claim 18, further comprising a propellant that is adapted to propel the projectile from the casing.

20. The cartridge of claim 18, wherein the casing is formed from a material selected from the group consisting of brass, aluminum alloy and plastic.

21. A projectile comprising:

a toughened polymer resin;

a curative agent by which the toughened polymer resin is cured; and

a particulate filler distributed through the toughened polymer resin, the particulate filler having a density greater than a density of the toughened polymer resin;

wherein the particulate filler is 70 to 80 percent by weight of the total projectile composition.

22. The projectile of claim 21, wherein the projectile has an average density that is less than the density of lead.

23. The projectile of claim 22, wherein the toughened polymer resin is 20 to 30 percent by weight of the total projectile composition.

24. The projectile of claim 21, wherein the projectile has an average density that is less than 45 percent of the density of lead.

25. The projectile of claim 21, wherein the particulate filler includes copper.

26. The projectile of claim 21, wherein the projectile is substantially lead-free.

27. The projectile of claim 21, wherein the particulate filler includes a material selected from the group consisting of copper, tungsten, lead, iron and steel.

28. A cartridge including a casing and the projectile of claim 21, with the projectile projecting from an end of the casing.

29. The cartridge of claim 28, further comprising a propellant that is adapted to propel the projectile from the casing.

30. The cartridge of claim 28, wherein the casing is formed from a material selected from the group consisting of brass, aluminum alloy and plastic.
