The invention relates to the technical field of composite plates for an automobile body, and particularly discloses a lightweight composite reinforcing plate for an automobile body and a preparation method thereof. The composite reinforcing plate comprises a composite main body shell plate capable of being installed on an automobile frame, a pre-embedded reinforcing structure arranged in the composite main body shell plate, and an external reinforcing structure arranged outside the composite main body shell plate and is connected with the pre-embedded reinforcing structure, wherein the composite main body shell plate comprises a first main body which is in a cambered surface shell shape, and a second main body which surrounds the periphery of the first main body and serves as a flanging structure. The preparation method comprises the following steps: manufacturing the pre-embedded reinforcing structure; manufacturing mixed woven cloth, and preparing a mold; and laying the composite reinforcing plate. The lightweight composite reinforcing plate of the invention solves the problems of unbalanced mechanical properties and weak front impact resistance of conventional carbon fiber composite boards in the prior art.
