山西云冈经开区清洁能源产业园,一条崭新的生产线发出低沉的轰鸣。卷绕机上,数万根细丝般的黑色 纤维汇成一道道"乌亮河流",匀速流淌。 图为T1000碳纤维。(中国科学院山西煤炭化学研究所供图) "从'无米下炊'到'高端迭代',我们走了二十年。"中国科学院山西煤炭化学研究所副所长、项目负责人 张寿春说,这抹亮丽的黑色背后,是一场持久的材料创新攻坚。 碳纤维,强度远超钢铁,重量轻如羽翼,被誉为"黑色黄金"与"新材料之王",是高性能、轻量化复合材 料结构件的优选之材,其研制涉及多个学科,是一项流程长、难度大、成本高的系统工程。 中国科学院山西煤炭化学研究所正高级工程师、技术研发负责人经德齐介绍,2005年前后,一些国家加 紧对我国实施碳纤维技术封锁和产品禁运,导致我国高端领域使用碳纤维陷入"断粮"境地。 彼时,T300是日本东丽公司研发的碳纤维牌号,T代表拉伸强度,后面的数字越大,碳纤维的力学性能 指标就越高。横截面1平方毫米的T300碳纤维,可以吊起重约百公斤的物体。这样的性能,让它成为大 国重器的关键支撑。 碳纤维的"轻"承载的是技术突围的"重"。我国自20世纪70年代开展相关领域研究,一代代人扎根山西煤 化所, ...
中国碳纤维绝地反击:日美不卖,中国山西造

几批研究者孜孜不倦的付出,助力我国实现了高端碳纤维的「无中生有」和「由弱变强」,让中国碳纤 维从「被人卡脖子」,变成了今天的「占据全球产能的半壁江山」。 碳纤维曾被「两院院士」师昌绪形容为跟芯片一样重要的东西。 它的重量只有钢的四分之一,强度却是钢的七到十倍,太空环境下能耐受上千度的高温,零下两百度仍 能保持稳定。 这种优越的性能,让它成为「现代材料之王」。 往大了说,它可以制造洲际导弹和运载火箭的耐高温外壳,可以制造飞机的轻质航空机身,制造顶级跑 车里坚固的驾驶座舱。 还有风力发电的叶片、高铁的车头、氢能汽车的储氢罐,"低空经济"中的飞行器,碳纤维都不可或缺。 但是曾经,对于中国来说,碳纤维却是一个被死死卡住脖子的痛点。以日本东丽为首的日本和美国企 业,通过多年的技术垄断,占据了全球大部分市场份额。 01 2005年左右,因为高性能碳纤维是典型的「军民两用」敏感物资,日美对中国实行了出口管制。你能在 市场上买得到波音787,但买不到造飞机的用的高端碳纤维,更买不到背后的科研技术。 那几年,正值国产大飞机项目酝酿启动,国防武器高速发展,新一代运载火箭和卫星急需升级。很多高 端制造领域,图纸都画出来了,但因为缺 ...
