Problems solved by technology

[0004] According to the research results of various scholars, it can be found that the addition of nickel can make the copper layer obtained by electroless plating more uniform, but the current nickel-copper-phosphorus alloy plating on the surface of carbon fiber still stays in the first nickel plating and then copper plating or copper plating first. The step-by-step plating stage of post-nickel plating is relatively complicated, but there is no report on the electroless nickel-copper-phosphorus plating on the surface of carbon fiber with nickel and copper composite plating solution.

Embodiment 1

[0026] Experimental raw materials include: T300 polyacrylonitrile-based carbon fiber, copper sulfate, nickel sulfate, palladium chloride, stannous chloride, acetone, hydrochloric acid, and 65% nitric acid. First use a Soxhlet extraction device to extract the carbon fiber with acetone at 70°C for 4 hours, then dry it naturally, then soak it in 65% concentrated nitric acid for 40 minutes, take it out, and then rinse it repeatedly with deionized water until the pH value of the residual solution is the same as Before cleaning, the pH value of the deionized water is close to that of the water, and it is dried in an oven at a temperature of about 80°C. Put the roughened carbon fiber into the SnCl-containing 2 Sensitize in a sensitizing solution of 20g / L and 40ml / L hydrochloric acid for 15min, take it out, wash it with distilled water once, dry it, and then put it into the sensitization solution containing PdCl 2 0.25g / L, hydrochloric acid 2.5ml / L activation solution for 15min, tak...

Abstract

The invention discloses a method of nickel-copper-phosphor ternary alloy plating on a carbon fiber surface. The method comprises steps of degumming; coarsening; sensitizing-activating; putting a carbon fiber treated with sensitization-activation in a nickel-copper-phosphor plating solution for plating until end of reaction, removing, washing and drying; and placing the nickel-copper-phosphor solution in a 80 DEG C-85 DEG C constant temperature water-bath for insulation. A formula of the nickel-copper-phosphor solution comprises nickel sulfate 25-30g / L, copper sulfate 2.0-2.5g / L, sodium hypophosphate 24-27g / L and a complexing agent sodium citrate 55-60g / L, wherein a pH is 8.0-8.5. According to the method, a nickel-copper-phosphor ternary alloy plating on the carbon fiber surface can be obtained at one time, so that the method can not only simplify a nickel-copper-phosphor alloy plating technology, but also can be applied to metallization processing of other composite reinforcement.

Description

technical field [0001] The invention relates to a method for metallizing the surface of carbon fibers, in particular to a method for plating a nickel-copper-phosphorus ternary alloy on the surface of carbon fibers. Background technique [0002] Due to low density, high strength, high modulus, and high temperature resistance, corrosion resistance, fatigue resistance, creep resistance, electrical conductivity, heat transfer and small thermal expansion coefficient, carbon fiber is often used in composite material reinforcements, high-precision airborne radar, The precision navigation system and the frame and support of the optical measurement system and other fields. When carbon fiber and metal material are composited, the interfacial bonding of the composite material will be affected due to the wettability problem between the two. Surface metallization of carbon fiber is an effective method to solve this problem. Electroless nickel plating on carbon fiber surface is a comm...
