Abstract

The invention discloses a preparation method of a carbon fiber / copper composite material, belongs to the field of metal-based composite materials, and particularly relates to a technical scheme of a carbon fiber / copper composite material and a preparation method of the carbon fiber / copper composite material. The preparation method is characterized in that a porous carbon blank which is obtained by pressing short carbon fibers is taken as a prefabricated body; and a copper alloy is permeated to pores of the prefabricated body so as to make the copper alloy fully fill in the pores of the carbon blank, and finally the copper alloy-based carbon fiber / copper composite material which is in network continuous distribution is formed. The carbon fiber / copper composite material can be used as a friction material, a carbon body material, an ablative material, various sliding bearing bushes, a sliding block and even a biological material. Compared with other preparation methods of the carbon fiber / copper composite material, the preparation method uses a non-pressure infiltration method, is simple in process, low in cost and easy to industrialize, and can prepare the carbon fiber / copper composite material with high conductivity, excellent self-lubrication abrasion resistance, excellent thermal shock resistance and ablation resistance.

Description

technical field [0001] The invention discloses a carbon fiber / copper composite material and a preparation method thereof, belonging to the field of metal matrix composite materials, and specifically relates to a technical scheme of a carbon fiber / copper composite material and a preparation method. Background technique [0002] Carbon / copper composite material, as a metal matrix composite material integrating structure and function, is widely used in various industrial sectors because of its excellent electrical conductivity, thermal conductivity, wear reduction, and wear resistance, such as friction materials, oil-containing Bearings, electrical contact materials, conductive materials and mechanical parts materials, etc. Especially in recent years, with the development of railway high-speed and electrification, sliding conductive materials have developed rapidly. Carbon / copper composite materials have become the first choice for modern sliding conductive materials because o...
