Multilayered composites reinforced with steel sheets were tried to be fabricated using single-shot explosive welding technique. The experimental conditions for obtaining moderate bonding at every interface were investigated based on collision velocity (V_P) and kinetic energy loss by collision (△KE) calculated using finite-difference analysis. In case of aluminum base composite reinforced with stainless steel sheets with the same thickness of multilayered plates, the amount of energy dissipated by collision (△KE) should be regulated at a certain range by changing stand-off distances between plates. In case of aluminum and titanium base composite reinforced with maraging steel sheets, moderated welding is unable to be achieved when using the multilayered plates with the same thickness due to a large difference of tensile strength between the components. The use of multilayered plates with the same mass per unit area by regulating the thickness of multilayered plates was useful for obtaining moderate bonding as a means to decrease the difference of △KE at each collision of the plates.
