The strength and absorbed energy on CFRP-aluminum alloy hybrid bonded material were investigated under impact load. The effect of impact velocity was examined experimentally. In experiment, impact three point bending tests using Charpy impact tester were carried out. Two-ply CFRP was bonded adhesively the side, which was subjected to tensile load, of aluminum alloy. The impact velocity was changed as 1.5, 2.5, 3.5 m/s. The effect of the impact velocity was estimated concerning the strength and absorbed energy. The effect of the impact velocity was not remarkable on the aluminum alloy without CFRP. But, when the head speed was increased, the absorbed energy of CFRP-aluminum alloy hybrid specimen increased.
