The utility model discloses an anti-brittle-crack hard aluminum-plastic plate which comprises aluminum alloy plates on two sides, a PE (polyethylene) core material on the middle layer and a fluorocarbon resin coating coated on the surfaces of the aluminum alloy plates, square strips are arranged on the contact surfaces of the aluminum alloy plates and the PE core material at equal intervals, and ahard fiberboard is arranged in the PE core material. According to the utility model, the plurality of square strips and the plurality of grooves are formed on the aluminum alloy plates on the two sides of the aluminum-plastic plate through stamping, and the square strips on the two aluminum alloy plates are perpendicular to each other in arrangement direction, so that the aluminum-plastic plate has certain bending resistance in the transverse direction and the longitudinal direction, and the hardness of the middle layer is improved through the hard fiberboard arranged in the PE core material.Therefore, the aluminum-p
