Abstract. Shaped charge has been designed by replacing conventional monolithic liner with bimetallic liner to possibly enhance its penetration capability. A shaped charge with bimetallic liner formulated using aluminum as the outer cone and copper as the inner cone with cone angle of 520,liner thickness of 2.4mm and calibre of 60mm. Theoretically predicted performance parameters have been compared with that of experimentally determined such as penetration depth and jet tip / slug velocity. The experimental results are reasonably in good agreement with theoretically predicted values. Penetration depth and tip velocity exhibit 22.5% and 10.67% increase respectively in comparison with shaped charge using copper as monolithic liner.
