Embodiment 1
[0022] Step 1: Use 60K polyacrylonitrile-based carbon fiber and its high-temperature (2500-3300°C) graphitized graphite fiber and copper fiber to carry out three-dimensional three-dimensional weaving according to a certain ratio, and the proportion of copper is not less than 15%. (mass percentage), woven into a prefabricated body whose shape meets the requirements;
[0023] Step 2, brushing the bottom surface of the prefabricated body so that the surface is covered with a layer of fibers; the fiber length is 2-5 mm, and spraying a layer of copper powder on the fibers on the bottom surface of the prefabricated body;
[0024] Step 3, the substrate is derusted, decontaminated, and frosted, and then coated with a uniform thickness of conductive adhesive;
[0025] Step 4, spread the prefabricated body on the substrate, compact it, and heat-cure according to a special curing procedure;
[0026] Step 5, install the copper-impregnated carbon slide 1 and the above-mentioned flexible s...
Embodiment 2
[0028] Step 1, using polyacrylonitrile fiber as raw material, processing it into a felt according to the required thickness of 30 mm, after pre-oxidation and carbonization, and then graphitizing at a high temperature at 2500-3000 ° C to make graphite felt;
[0029] Step 2, cutting the graphite felt into the required size; wherein the width of the felt is 50mm;
[0030] Step 3, using molten metal high-pressure carbon impregnation technology to impregnate graphite felt with nickel to obtain nickel-impregnated graphite felt;
[0031] Step 4, spray a layer of copper powder on the bottom of the graphite felt;
[0032] Step 5, the substrate is derusted, decontaminated, and frosted, and then coated with conductive adhesive of uniform thickness;
[0033] Step 6, spread the prefabricated body on the base plate, compact it, and heat-cure according to a special curing procedure;
[0034] Step 7, install the copper-impregnated carbon slide 1 and the above-mentioned flexible slide 2 on t...
Embodiment 3
[0036] Step 1, use 48K polyacrylonitrile-based carbon fiber and its high-temperature (2500-3300°C) graphitized graphite fiber and copper fiber. The proportion of the three according to the copper (mass percentage) is not less than 35%, and the carbon fiber is not less than 25%. %, use the needle punching felting process to make graphite felt with a composite design of thickness, and then cut it into the required size, wherein the width is 40mm;
[0037] Steps 2-5 correspond to steps 4-7 in Embodiment 2.
