Abstract

A projectile includes a toughened polymer resin, a curative agent and a particulate filler. The curative agent cures the toughened polymer resin. The particulate filler is distributed throughout the resin. The particulate filler has a density greater than a density of the resin. The particulate filler can be 70 to 80 percent by weight of the total projectile composition. The particulate filler can include at least one of copper, tungsten, lead, iron and steel. The projectile has an average density that is less than the density of lead. Additionally, the toughened polymer resin can be 20 to 30 percent by weight of the total projectile composition.

Claims

1. 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.

2. The projectile of claim 1, wherein the projectile has an average density that is less than the density of lead.

3. The projectile of claim 2, wherein the toughened polymer resin is 20 to 30 percent by weight of the total projectile composition.

4. The projectile of claim 1, wherein the projectile has an average density that is less than 45 percent of the density of lead.

5. The projectile of claim 1, wherein the particulate filler includes copper.

6. The projectile of claim 1, wherein the projectile is substantially lead-free.

7. The projectile of claim 1, wherein the particulate filler includes a material selected from the group consisting of copper, tungsten, lead, iron and steel.

8. A cartridge including a casing and the projectile of claim 1, with the projectile projecting from an end of the casing.

9. The cartridge of claim 8, further comprising a propellant that is adapted to propel the projectile from the casing.

10. The cartridge of claim 8, wherein the casing is formed from a material selected from the group consisting of brass, aluminum alloy and plastic.

11. A projectile comprising:

a toughened polymer resin; 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.

12. The projectile of claim 11, wherein the toughened polymer resin includes an elastomer-modified epoxy functional adduct.

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

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

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

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

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

18. The cartridge of claim 17, further comprising a propellant that is adapted to propel the projectile from the casing.

19. The cartridge of claim 17, wherein the casing is formed from a material selected from the group consisting of brass, aluminum alloy and plastic.

20. A projectile comprising:

a toughened polymer resin including an elastomer-modified epoxy functional adduct;

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, the particulate filler including a material selected from the group consisting of copper, tungsten, iron and steel;

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

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

wherein the projectile is substantially lead-free and has an average density that is less than 45 percent of the density of lead.
