[0060] In this embodiment, the method for carbon fiber recycling using a two-step solar system for recycling carbon fibers includes the following steps:

[0061] 1) A piece of waste composite carbon fiber with a size of 200mm×200mm×4.5mm square is used.

[0062] 2) Place the carbon fiber sample of step 1) on the sample processing platform 4 for pretreatment.

[0063] 3) The temperature of the light spot on the carbon fiber sample processing platform 4 is stabilized at 500°C through a digital device.

[0064] 4) Move the carbon fiber sample processing platform 4 of step 3) in the X-axis and Y-axis directions, so that the waste composite carbon fiber material is evenly heated, and the front and back sides are irradiated for 10 minutes each.

[0065] 5) Take out the carbon fiber sample that has been irradiated in step 4), and put it into the heating box 5 for finishing.

[0066] 6) The temperature in the heating box 5 is stably controlled at 550°C through the digital device, and the carbon ...

Description

Technical field [0001] The present invention relates to the technical field of carbon fiber material recycling, in particular to a solar energy system and method for recycling carbon fiber by adopting a two-step method. Background technique [0002] Carbon fiber materials have the characteristics of light weight, high mechanical strength, good corrosion resistance and low thermal expansion, and are widely used in aerospace, automotive, construction, communications and other industrial fields. With the rapid development of aerospace, automobile manufacturing, sporting goods and other industries, the demand for carbon fiber materials is increasing day by day. Although carbon fiber materials have many excellent properties, their wastes are not biodegradable. If they cannot be properly treated and effectively recycled, they will not only cause serious environmental pollution, but also cause great waste of precious carbon fiber materials. In Europe, about 1,100 tons of waste carbon f...
