2008年世界高性能纤维保持高速增长的势头,但金融危机后需求量有所下降。文中介绍了碳纤维、芳酰胺纤维、高强聚乙烯纤维、玄武岩纤维、PBO纤维、PPS纤维产能扩大、新品种、新工艺和新用途的开发情况。在我国上述纤维均取得了重要的进展,纷纷迈向产业化,同时市场竞争开始加剧。 In 2008, the world high-performance fiber maintained the momentum of rapid growth, but the demand declined after the financial crisis. The paper introduces the development of carbon fiber, aramid fiber, high strength polyethylene fiber, basalt fiber, PBO fiber and PPS fiber, and the development of new varieties, new techniques and new uses. In our country, the above fibers have made important progress, one after another towards industrialization, and the market competition began to intensify.
