Problems solved by technology

[0003] In the course of the research, the inventor found that the existing carbon fiber copper plating process cannot well meet the performance requirements of the blade material of the electrothermal deicing wind turbine, because the working environment of the wind turbine is harsh day and night and the temperature difference between different seasons is large. , electrical terminals require carbon fiber and copper plating to have a higher bonding force and good electrical conductivity

Abstract

The invention relates to an electroless copper plating method for carbon fibers. The electroless copper plating method comprises the steps of carbon fiber preprocessing and electroless copper plating. In the preprocessing step, an acetone method is mainly used for ungluing, and the carbon fibers are processed through a sensitization and activation one-step method. In the electroless copper plating step, a plating solution is mainly composed of copper sulfate pentahydrate, tetrahydroxypropyl ethylenediamine, edta disodium, formaldehyde, bispyridine, potassium ferrocyanide and PEG-100. The pH value is controlled within 10-13. By means of the electroless copper plating method, copper-coated carbon fibers can be quickly obtained, a copper plating layer and the carbon fibers are tightly combined, and the plating layer is even and can reach a certain thickness. The combining capacity between the carbon fibers and the copper plating layer can be improved, and therefore the carbon fibers can adapt to a poor working condition of a wind driven generator.

Description

technical field [0001] The invention relates to a method for plating copper on the surface of carbon fibers. technical background [0002] Carbon fiber is a new type of high-strength and high-modulus fiber material with a carbon content of more than 95%. It is widely used for its thermal conductivity, electrical conductivity, high temperature resistance, and fatigue resistance. The domestic demand for carbon fiber increasing day by day. Electroless plating uses a reducing agent to reduce and deposit metal ions on the base material, and there is no limit to the shape of the base material. Utilizing the convenience brought by electroless plating technology while overcoming the limitations of the single material performance of carbon fiber, a layer of copper is obtained on the surface of carbon fiber, so that carbon fiber not only has its own excellent characteristics, but also has the advantages of metal copper conductivity and good weldability. [0003] In the course of the...
