联合碳化物公司是美国研制生产碳纤维最大的一家公司,过去主要研制生产粘胶丝碳纤维,近年来重点研究沥青碳纤维,同时也发展聚丙烯睛碳纤维。该公司是世界上第一个用石油沥青研制生产碳纤维的公司,也是目前世界上唯一能生产高性能沥青碳纤维的公司,1981年底已在美国南卡罗来州的格林维尔建成年产50万磅沥青碳纤维的生产线,同时还在该地建设生产能力为100万磅/年的聚丙烯腈碳纤维装 Union Carbide Corporation is the United States to develop and produce the largest carbon fiber company, in the past the main development and production of viscose carbon fiber, in recent years focused on asphalt carbon fiber, but also the development of polypropylene carbon fiber eyes. The company is the world’s first company to develop and manufacture carbon fibers from petroleum pitch and is the only company in the world capable of producing high-performance pitch carbon fiber. At the end of 1981, it was completed in Greenville, SC, with an annual output of 500,000 pounds Asphalt carbon fiber production line, while also building a production capacity of 1 million pounds / year polyacrylonitrile carbon fiber equipment
