碳纤维、聚酰胺纤维等尽管价格昂贵,但由于有极好的综合特性,近年来发展十分迅速,并广泛地用于纤维增强复合材料的各领域。最近英国 Leeds 大学又成功地研制出了高分子量的聚乙烯纤维,并由荷兰的 DSM 公司成功地进行了商业性生产,1989年的产量还十分有限,仅为几百吨,但目前一些在建的项目将会使这种新型纤维的产量在1990年增加十几 Although carbon fiber, polyamide fiber, and the like are expensive, due to their excellent comprehensive characteristics, they have been rapidly developed in recent years and are widely used in various fields of fiber-reinforced composite materials. Recently, Leeds University in the UK successfully developed high-molecular-weight polyethylene fibers, and the Dutch DSM company successfully carried out commercial production. In 1989, the production was still very limited, only a few hundred tons, but some are currently under construction. Project will increase the output of this new fiber by more than a dozen in 1990
