Ammunition cartridge case bodies made with polymeric nanocomposite material
First Claim
1. A three-part ammunition cartridge casing body comprising:
- a base portion, made of metal or polymeric resin, having a closed end and an open end;
a substantially cylindrical case portion, open on both ends, joined to the open end of the base portion and comprising a nanocomposite material of a nanoclay dispersed in a polyamide resin matrix; and
a cap portion, made of a nanocomposite material of a nanoclay dispersed in a polyamide resin matrix and glass fibers, joined to the other end of the case portion, wherein the case portion is materially different from and more ductile than the cap portion.
