Abstract

The invention relates to a method for chemically plating nickel on the surface of carbon fiber. The invention aims to solve the problem that the existing method for chemically plating the nickel on the surface of the carbon fiber causes environment pollution, is unstable in activation fluid, complex in operation, and low in plating layer bonding intensity. The method comprises the following steps of: 1, firstly, removing glue and oil from the surface of the carbon fiber; 2, soaking in concentrated nitric acid for coarsening, then washing by distilled water under the help of ultrasound, and finally drying into constant weight, so that the cleaned and coarsened carbon fiber can be obtained; 3, firstly, soaking the obtained product in the activation fluid, then washing by distilled water and soaking in sodium borohydride solution to be reduced, and finally rewashing by distilled water, so that the activated carbon fiber can be obtained; and 4, soaking into chemical nickel-plating liquid, withdrawing, and washing by distilled water, and then drying into constant weight, so that the nickel can be chemically plated on the surface of the carbon fiber. The method for is mainly used for chemically plating the nickel on the surface of the carbon fiber.

Description

technical field

[0001] The invention relates to a method for nickel-plating the surface of carbon fiber. Background technique

[0002] Carbon fiber is a new type of anisotropic reinforced material with high specific strength (3-7GPa), high specific modulus (200-650GPa), light weight (1.7g / cm 3 ~2.0g / cm 3 ), small coefficient of thermal expansion (0~-1.1×10 6 K -1 ), good mechanical properties (it has a certain reinforcing effect on polymers), fatigue resistance, less carbon spalling and many other excellent properties, which are widely used in the field of composite materials. However, since the carbon and carbon on the surface of the carbon fiber are connected by non-polar covalent bonds, there is a random layer structure of parallel graphite crystallites between the grain boundaries, resulting in poor wettability, poor compatibility with metals, and difficulty in forming Strong interfacial bonding, so carbon fiber has been limited to a certain extent in the field of co...
