Carbon fiber surface plating system

Abstract

The present invention relates to a carbon fiber production apparatus and especially relates to a continuous carbon fiber surface electroplating system. The carbon fiber surface electroplating system comprises a carbon fiber creel and a carbon fiber winder, and is characterized in that an electroplating treatment device is arranged between the carbon fiber creel and the carbon fiber winder, a carbon fiber comes out from the carbon fiber creel and passes through the electroplating treatment device, the electroplated carbon fiber is then wound up by the carbon fiber winder, the electroplating treatment device comprises an anode tank and at least one cathode tank, the cathode tank is internally provided with a cathode graphite plate while the anode tank is internally provided with an anode graphite plate, the cathode graphite plate and the anode graphite plate are connected with a negative electrode and a positive electrode of a power supply respectively, the distance between the carbon fiber and the cathode graphite plate is less than 3 mm, and the distance between the carbon fiber and the anode graphite plate is between 50 mm and 100 mm. In an electroplating process, the carbon fiber does not need to pass any guide rollers, so friction of the carbon fiber in the electroplating process is reduced, production of burrs is decreased, and the product quality is improved.

Description

technical field [0001] The invention belongs to carbon fiber production equipment, in particular to a continuous carbon fiber surface electroplating system. Background technique [0002] As a high-tech material, carbon fiber is widely used in aerospace and civil fields. It is considered to be the most promising reinforcing fiber at present. At present, more than 90% of carbon fiber in the world is produced by polyacrylonitrile precursor. Metallized carbon fiber not only has the excellent mechanical properties of carbon fiber, but also has the excellent electrical conductivity of metal. The specific resistance of general metal is much lower than that of carbon fiber: the specific resistance of carbon fiber is usually 10 -2 -10 -3 Ω·cm, the resistance of metallized carbon fiber is 10 -5 Ω·cm is close to the specific resistance of most metals (10 -6 Ω cm), the composite material prepared by metallized carbon fiber can significantly reduce the specific resistance of the comp...

Problems solved by technology

Many domestic researches focus on electroless plating, which has little guiding effect on industrial production

In addition, carbon fiber is a brittle material, and it is easy to produce hairs during production and subsequent use. Traditional electroplating equipment cannot be used for carbon fiber performance electroplating. It is necessary to specially design the transmission device and point solution tank according to the performance characteristics of carbon fiber to avoid electroplating. The process produces fuzz, which in turn affects the quality of the product
