Manufacturing and Evaluating for the Two Layer/Explosive Materials and Their Numerical Simulations

摘要

Combination of different materials used in the liner of the shaped charge is of great importance in designing for maximization of energy transfer. In general, a Cu liner is widely used for the special purpose in military as well as in industry. The reactive Cu liners require excellent mechanical properties and reactivity of the energetic materials. Pure Al powders are widely known as energetic materials. In this regard, the integrated work was done based on the three procedures. First, the kinetic-sprayed Al coating was fabricated on Cu substrate to generate a reactive Cu liner. And the reactivity, bonding and mechanical properties of kinetic-sprayed Al coatings were investigated. Second, the experimental evaluation of kinetic-sprayed Al coatings in terms of the strain rate. Finally numerical modeling and simulation were carried outand discussed for visibility validation.
