The invention relates to an aluminum alloy laminated armor and a manufacturing method thereof, and belongs to design and manufacture methods of armors. The aluminum alloy laminated armor sequentiallycomprises a soft layer, a connecting layer, a hard layer, a connecting layer and a soft layer from one side of the bullet facing surface, or sequentially comprises a soft layer, a connecting layer anda hard layer from one side of the bullet facing surface; and the soft layer, the connecting layer and the hard layer are all made of aluminum alloy materials. The bullet facing surface of the laminated armor is an aluminum alloy with good plasticity and toughness, the middle of the laminated armor is an aluminum alloy with high hardness and strength, and connecting transition between the bullet facing surface and the middle is achieved through a 1000 series aluminum alloy. The aluminum alloy laminated armor is formed by compound pressing of different aluminum alloy plates. According to the aluminum alloy laminated armor, design is ingenious, advantages of the different materials are exerted aiming at the bullet-proof property of the armor, the manufacturing process is simple, and application and popularization are facilitated.
