The invention discloses an aluminum alloy crash box for an automobile. The aluminum alloy crash box for the automobile comprises an aluminum alloy crash box body, wherein the aluminum alloy crash box body is filled with long fiber reinforced thermoplastic composite material blocks; and connecting plates are arranged at the two ends of the aluminum alloy crash box body. Preferably, two types of long fiber reinforced thermoplastic composite material blocks with different densities are arranged in the aluminum alloy crash box body at intervals. According to the invention, as the aluminum alloy crash box body is combined with the long fiber reinforced thermoplastic composite material blocks, the energy absorption properties of the aluminum alloy crash box body and the long fiber reinforced thermoplastic composite material blocks are organically combined and composite materials with a plurality of densities are arranged in the aluminum alloy crash box body at intervals to control the deformation mode of the crash box; therefore, the energy absorption potential of the crash box is maximized. Automobile crash damage and personal injury can be effectively reduced.
