Embodiment 1
[0040] A method for preparing a composite metal layer-plated foamed copper / carbon fiber composite material of the present invention includes the following steps:
[0041] (1) Add carbon fiber with a length of 0.1μm and a purity of 99% into the acid solution, heat it to reflux in a water bath at 80°C for 2h, and then dilute with deionized water and wash to neutrality. After separation and drying, the acidified The ratio of the mass of carbon fiber to the volume of the acid is 2:100g / mL, and the acid is made by mixing 98% of concentrated sulfuric acid and 65% of concentrated nitric acid in a volume ratio of 3:1;
[0042] (2) Add the acidified carbon fiber to the sensitizer solution and ultrasonically treat it for 30 minutes, then dilute it with deionized water and wash to neutrality, and then separate and dry to obtain the sensitized carbon fiber; the quality of the carbon fiber and the sensitizer solution The volume ratio is 2:100g / mL, the sensitizing solution is 100mL deionized wat...

[0051] A method for preparing a composite metal layer-plated foamed copper / carbon fiber composite material of the present invention includes the following steps:
[0052] (1) Add carbon fiber with a length of 0.3μm and a purity of 99% to the acid solution, heat it to reflux for 2h in a water bath at 80°C, and then dilute with deionized water and wash to neutrality. After separation and drying, the acidified The carbon fiber; the ratio of the mass of carbon fiber to the volume of the acid is 3:100g / mL, and the acid is made by mixing 98% of concentrated sulfuric acid and 65% of concentrated nitric acid by volume at a volume ratio of 3:1;
[0053] (2) Add the acidified carbon fiber to the sensitizing solution and ultrasonically treat it for 30 minutes, then dilute it with deionized water and wash it to neutrality. After separation, dry it at 70°C for 24 hours to obtain the sensitized carbon fiber; the quality and sensitivity of carbon fiber The volume ratio of the chemical solution is...
