Abstract:

The use of lead projectile cores in current U.S. Army small caliber ammunition has caused increasing concern over the environmental contamination of military firing ranges and surrounding areas. A number of military firing ranges are in danger of being closed due to high levels of lead contamination. TRI/Austin proposes to demonstrate the feasibility of developing a non-toxic, lead free, cost effective, injection molded projectile core made from a high density powder metal alloy combined with a state-of-the-art polymer binder. Compatible polymer binders with excellent adhesion will be determined by using a unique method to characterize the surface charge or zeta potential of the metallic particle surface. The powder metal alloy-polymer core will have a density similar to a lead core and will perform ballistically like a lead core. Polymer binders such as polyetherimide, polypthalimide, nylon 6,6 nylon 11 and nylon 12 will be mixed with a metal alloy such as tungsten-copper for injection molding. Degradation additives will be investigated to accelerate the polymer binder's degradation once the projectile core is spent.
