Abstract

The invention relates to FeCo alloy / CuO double-plating magnetic carbon fiber and a preparation method and application. FeCo alloy and Cu plating are successively electroplated on the surface of the pretreated continuous carbon fiber by use of the traditional electroplating means, CuO plating is formed after thermal oxidation, and columnar CuO with diameter of about 100 nm is formed on the surface. The electromagnetic parameters of the carbon fiber are improved through the alloy / oxide double-plating; the modified magnetic carbon fiber has high-frequency and high-strength microwave absorption performance, and has microwave loss of less than -10 dB at the frequency band from 2-18 GHz; and when the frequency is 9.6 GHz, the composite material with thickness of only 1.6 mm shows the maximum microwave absorption valve of -47.56 dB. The magnetic carbon fiber provided by the invention has uniform and dense magnetic double-plating, is simple in preparation process, high in production efficiency and excellent in microwave absorption performance, and can be used as a novel low-density microwave absorption material.

Description

technical field

[0001] The invention belongs to the field of microwave absorbing materials, in particular to a FeCo alloy / CuO double-coated magnetic carbon fiber, a preparation method and application. Background technique

[0002] The conductivity of carbon fiber is between non-metal and metal, with small thermal expansion coefficient, low density, high strength and modulus, no creep, fatigue resistance, and corrosion resistance. It can be used as an excellent structural absorbing material. Theoretically speaking, good microwave absorption performance requires the material to have high electrical loss and magnetic loss, but carbon fiber itself is not magnetic. An efficient approach to performance. Compared with surface metallization methods such as sputtering, ion plating, metal powder spraying, metal coating, and electroless plating, the electroplating method has simple equipment, low cost, continuous production, and has a good application prospect. Electroplating of sing...
