Abstract

The invention discloses a method for nickeling a carbon fiber / cyanate ester resin composite material. The method comprises the following steps: pre-nickeling the surface of a pretreated carbon fiber / cyanate ester resin composite material through a chemical plating method, and then, nickeling by using an electroplating method. According to the method, chemical plating is combined with electroplating, the pre-nickeling procedure is carried out by the chemical plating method firstly to form a uniform conductive layer on the material surface, and then, the nickel layer is thickened by the electroplating method to both ensure the uniformity of the nickeling layer and ensure enough thickness for the nickeling layer, the problems of plating leakage and too thin plating layer when nickeling the surface of the carbon fiber / cyanate ester resin composite material in the prior art are solved, uniform and thick enough plating layer is obtained, the plating layer is uniform, integral, free of plating leakage phenomenon, good in binding force with a base material, free of gap and capable of meeting the application conditions of a space optical mirror, and the electroplating and chemical plating production costs are low, so that volume production can be realized.

Description

technical field [0001] The invention belongs to the technical field of surface treatment of non-metallic materials, and in particular relates to a nickel-plating method for a carbon fiber / cyanate resin composite material. Background technique [0002] Remote sensing is the main means to realize the detection of military targets, and the level of remote sensing cameras determines the modernization level of a country's national defense. Since the 1980s, remote sensing cameras have been competing to develop among countries all over the world. The most representative ones are the US SPOT5 (2001, 2.5-meter resolution), IKNOS (1999, 1-meter resolution), KH-12 ( In 2007, 0.1-meter resolution) and other cameras can detect the number of pedestrians and vehicles on the ground and sensitive areas, greatly improving the level of detail of military intelligence, so large-caliber high-resolution remote sensing cameras are the needs of future military struggles. However, the improvement o...
