Ammunition round with frangible projectile

Abstract

A projectile has a particulate filler distributed in a toughened polymer resin and composite mixture in which the composite mixture is melted or mixed with a curative agent or foaming agent prior to injection or pouring into a mold, usually under pressure. The particulate filler has a density greater than a density of the resin and can include metals and additives to add weight and other mechanical properties to the composite mixture. The polymer resin can be about 3% to about 30% by weight of the total projectile composition having an average density less than the density of lead. The particulate filler can be about 70% to 97% by weight of the total projectile composition and can include copper, tungsten, lead, brass, iron, bismuth, and/or steel.
