Aluminum veneer material with high tensile strength and preparation method thereof

The invention relates to the technical field of aluminum veneer materials, in particular to an aluminum veneer material with high tensile strength and a preparation method thereof. The composite material comprises aluminum-based alloy layers and a reinforced fiber layer, the two aluminum-based alloy layers are arranged up and down, and each aluminum-based alloy layer at least comprises the following raw materials in percentage by weight: copper, silicon, magnesium, zinc, titanium, iron, rare earth elements and the balance of pure aluminum; the reinforced fiber layer comprises the following raw materials: silicon carbide fiber, boron fiber and alumina fiber; the reinforced fiber layer is made of the silicon carbide fibers, the boron fibers and the aluminum oxide fibers, so that the tensile strength of the aluminum veneer material is improved, and meanwhile, the corrosion resistance, the wear resistance, the high-temperature usability and the fatigue resistance of the aluminum veneer material are well improved.
