To improve the penetration depth in the target subjected to the jet of reactive materials liner， a shaped charge with Al/Ni-Cu double-layered reactive liners based on the K-charge structure was proposed. The outer and inner liner of the double-layered reactive liner are made of oxygen-free copper and Al/lNi reactive material， respectively. Experimetal study of jet formation， static armor-piercing into steel ingots and the penetration power to typical concrete targets were carried out seperately by using X-ray cinematography. Results show that the double-layered reactive liners with K-charge can form a continuous jet after detonation with obvious pit areas in steel and concrete targets. However， the jet has no obvious reaming effect on penetrating the target. A combined damage effect of kinetic energy and chemical reaction can be achieved by the Al/Ni-Cu double-layered reactive liners. Compared with the Cu-Cu double-layered， less jet accumulated in the target penetrated by the new double-layered reactive linears. Meanwhile， the penetration depth and volume of the steel targets were increased by 20.1% and 23.0%， respectively， while the penetration depth and volume of the concrete targets were increased by 17.2% and 45.6%， respectively.
