Study on the explosive formed projectile liners

Armorpiercing tests of three explosive formed projectile (EFP) shaped charges of the same shape and size were conducted under the same charging condition. Tungstencopper power alloys, copper and copperaluminum composite were used as the liner materials. With a body size hole on the top of the copperaluminum composite liner, the armorpiecing capability of the EFP shaped charge is 22% better than that of copper liner EFP. The fragments formed were regular.
