国内现有近40家企业和研究所投入建设碳纤维生产线,但国内单线产能到达千吨级并投产的企业只有3家,并且大部分碳纤维企业只有一、两条生产线,存在品种规格单一、能耗高、工位少、生产速度慢等问题。因此,我们必须向新材料高新产业转型升级。 Nearly 40 domestic enterprises and research institutes have invested in the construction of carbon fiber production lines. However, there are only 3 domestic enterprises that have single-line production capacity reaching the 1,000-ton level and have put into operation. Most of the carbon fiber enterprises have only one or two production lines with single specifications and energy consumption High, less workstations, slow production and other issues. Therefore, we must transform and upgrade the new material and high-tech industries.
