Abstract

The invention discloses a carbon fiber cloth-aluminum alloy compound material and a preparation method thereof. The carbon fiber cloth-aluminum alloy compound material is obtained by cladding carbon fiber cloth with copper and then casting aluminum alloy. The preparation method comprises the following steps: 1) pre-treating the carbon fiber cloth; 2) cladding the carbon fiber cloth with copper: cladding the surface of the carbon fiber cloth with the copper according to a chemical plating or electroplating method; 3) preparing a casting mould,wherein the casting mould is prepared according to the demand on the arrangement of the carbon fiber cloth in the aluminum alloy; and 4) smelting the aluminum alloy and casting, thereby lastly obtaining the carbon fiber cloth-aluminum alloy compound material in required shape. The carbon fiber cloth-aluminum alloy compound material prepared according to the preparation method is excellently compounded; the components of the aluminum alloy are adjustable; the distribution of the carbon fiber cloth is controllable; and the compound material has higher specific modulus, low density and high specific strength, and is suitable for the building field and the protecting field.

Description
