根据国内主要超高分子质量聚乙烯纤维制造商产品的测试结果,论述了国产该纤维的主要性能及其与国外同类产品的质量差距,论述了目前我国各生产厂家及相关检测机构在强度、模量、断裂伸长、耐磨性、蠕变率、分子质量等纤维主要性能测试中存在的问题,提出了解决建议,同时指出了我国在超高分子质量聚乙烯纤维应用方面与国外的差距. According to the test results of the products of major domestic manufacturers of UHMWPE fibers, the main properties of the fibers made in China and the quality gap between them and the same kind of foreign products are discussed. At the present, Quantity, elongation at break, abrasion resistance, creep rate, molecular weight and other problems in the testing of the main properties of the fibers, put forward solutions to the problems and pointed out the gap between China and foreign countries in the application of ultra-high molecular weight polyethylene fibers.
