日本东丽公司1982年碳纤维生产能力达到1260吨/年。在提高产量的同时,东丽公司十分注意提高产品质量。以碳纤维T300为例,73年东丽公司提供的性能数据是抗拉强度>250公斤/毫米~2,断裂延伸率为0.9—1.2％;七十年代末抗拉强度提高到300—320公斤/毫米~2,断裂延伸率为1.3％;今年七月东丽公司来华进行技术座谈时提供数据,其抗拉强度又提高到340—360公斤/毫米~2,断裂延伸率为1.4—1.5％。除此以外又发展了高强碳纤维新品种T400,它的抗
Toray Japan’s carbon fiber production capacity in 1982 reached 1,260 tons / year. While increasing the output, Toray pays great attention to improving product quality. Taking carbon fiber T300 as an example, the performance data provided by Toray for 73 years is that the tensile strength is> 250 kg / mm ~ 2 and the elongation at break is 0.9-1.2%; the tensile strength at the end of 1970s is increased to 300-320 kg / Mm ~ 2, elongation at break of 1.3%; in July this year, Toray to provide technical discussions in the discussion data to provide the tensile strength was increased to 340-360 kg / mm ~ 2, the elongation at break of 1.4-1.5% . In addition to the development of a new high-strength carbon fiber T400, its resistance
