不断扩大的碳纤维需求及其对策

2004年以来，建筑补强材料、新型民航机、风力发电叶片和压力容器等方面对碳纤维的需求不断扩大，迎来了碳纤维复合材料的新时代．日本3家PAN基碳纤维公司一起分阶段增大产能，预期到2010年东丽集团的产能约1．8万t/a，东邦和三菱各将接近1万t/a，世界总产能可望达到4．8万t/a．由于市场供不应求，价格不断攀升，各碳纤维厂家盈利大增，为我国加速发展碳纤维及其复合材料产业提供了难得的历史机遇．今后不断降低生产成本是重要的课题，以期进一步扩大应用于汽车、能源等一般产业的领域，达到持续发展的目的．

Expanding demand of carbon fiber and countermeasures

The demand of carbon fiber in reinforeing constructure, new type airplane, wind will blade and pressure container are expanding since 2004, the times of carbon fiber composite material is comming. 3 Japanese carbon fiber companies are all expanding their capacities step by step, the capacity of toray group will reach about 18 000t/a, while toho-tenax and mits bishi group will reach near 10 000t/a, the total capacities of the world will reach about 48 000t/a in 2010 according to the predict. The prices of carbon fiber are rising again and again due to the tight of providing carbon fiber, so the benefit of these carbon fiber companies raises guickly, these are the historical chances for china to develop carbon fiber and it's CFRP industry. The main important course hearafter is to reduce the cost of carbon fiber, in order to use in automobile, energy cources and other industrial fields.
