报告大纲：

    PAN-carbon fibers have attracted growing attention in recent years due to their high tensile strength,lightweight, superior chemical and electrical properties. Manufacturing of carbon fibers from the PAN process: 1. Spinning: PAN mixed with other ingredients and spun into fibers. 2. Stabilizing: Chemical alteration to stabilize bonding. 3. Carbonizing: Stabilized fibers heated to very high temperature forming tightly bonded carbon crystals. 4. Treating the surface: Surface of fibers oxidized to improve bonding properties. 5. Sizing: Fibers are coated and wound onto bobbins. Meanwhile, the manufacture of carbon fibers carries a number of challenges, including: The need for more cost effective recovery and repair. The surface treatment process must be carefully regulated to avoid creating pits that could result in defective fibers. Close control required to ensure consistent quality. Because of carbon fibers have superior properties, it may play an increasingly important role in areas such as aerospace, sports, automotive, wind energy, oil and gas, infrastructure, defense, semiconductors and so on.
