Description

technical field [0001] The invention relates to the technical field of carbon fiber material recycling, in particular to a solar energy system and method for recycling carbon fiber using 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, automobile, construction, communication 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 waste cannot be biodegraded. If they cannot be properly disposed of and recycled effectively, it will not only cause serious environmental pollution, but also cause a great waste of valuable carbon fiber materials. In Europe, about 1,100 tons of waste carbon fiber ne...
