Abstract

The invention relates to a nickel coating carbon fiber composite material and a preparation method thereof. The preparation method comprises the following steps: preprocessing a carbon fiber material, depositing a nickel coating of 1 nm to 5 nm on the processed carbon fiber material by a chemical plating, CVD (chemical vapor deposition) or MOCVD (metal organic chemical vapor deposition) method, soaking the nickel-coated carbon fiber material in prepared phenolic resin, epoxy resin, cyanate ester resin or bismaleimide resin to form prepregs, properly trimming the two or more layers of prepregs, putting into a mould, and performing hot press molding in a hot press under the pressure of 30-60 MPa. The preparation method adopts a hot press molding process and is high in production efficiency, low in cost and suitable for large-scale production; the prepared nickel coating carbon fiber composite material is remarkably improved in electromagnetic performance while keeping the characteristics of high strength and light weight.

Description

technical field [0001] The invention relates to a carbon fiber composite material, in particular to a nickel-coated carbon fiber composite material and a preparation method thereof. Background technique [0002] Carbon fiber is a fibrous carbon material with excellent mechanical properties. Its strength and modulus greatly exceed general fiber materials such as polyester fiber, glass fiber, ultra-high molecular weight polyethylene fiber, silicon carbide fiber and aluminum silicate fiber. It is a commonly used reinforcing fiber for composite materials. The carbon fiber industry plays an important role in the upgrading of pillar industries in developed countries and the improvement of the overall quality of the national economy. It is also of great significance to the adjustment of my country's industrial structure and the upgrading of traditional materials. Advanced carbon fiber composites play an important role in aviation, aerospace, military, construction and other fields...
