Embodiment
[0050] A method for preparing a gold coating on the surface of a carbon fiber reinforced resin-based composite material. The method is to prepare a gold coating on the surface of a carbon fiber reinforced cyanate ester composite material. The specific steps are:
[0051] 1) Wipe the surface of the carbon fiber reinforced resin matrix composite material so that the surface of the carbon fiber reinforced resin matrix composite material is completely wetted by water and the water film is continuous within 30s;
[0052] 2) The surface of the carbon fiber reinforced resin-based composite material obtained in step 1) is chemically roughened, and the formula and operating conditions of the chemical roughening solution are as follows:
[0053]
[0054]
[0055] After the chemical roughening is completed, the carbon fiber reinforced resin matrix composite is taken out of the solution;
[0056] 3) washing the residual solution on the surface of the carbon fiber reinforced resin-base...
