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.
