摘要（英）：

The invention relates to a copper-nanpsilicon carbide-aluminum sandwich structure composite material and a preparation method thereof. According to the technical scheme, the preparation method sequentially comprises the following steps: preprocessing nanpsilicon carbide powder; carrying out surface roughening on a to-be-machined copper material and a to-be-machined aluminum material; assembling acopper-nanpsilicon carbide-aluminum sandwich structure; carrying out composite rolling on the copper-nanpsilicon carbide-aluminum sandwich structure; carrying out stabilizing treatment on the rolled copper-nanpsilicon carbide-aluminum sandwich structure material; and preparing the copper-nanpsilicon carbide-aluminum sandwich structure composite material. The method has the characteristics of simple process, short production period and low preparation method, the prepared product is high in strength, low in thermal expansion coefficient, corrosion resistance, high surface mechanical meshing level, strong plastic deformation capacity and good bonding strength.
