The collisional processes of differentiated parent bodies in the solar nebula play an important role to clarify the origin of iron meteorites and M-type asteroids. We conducted impact experiments on metal core-rocky mantle targets simulating iron meteorite parent bodies in order to study the collisional disruption and the formation condition of differentiated meteorite such as irons. We investigated the impact fragmentation and re-accumulation of the core-mantle bodies with different core/target mass ratios. We estimated the energy density partitioned into the core and the mantle using the energy fraction to clarify the internal structure is a crucial parameter to control the collisional outcomes of the core-mantle bodies.
