碳纤维产业中国专利分析研究

Analysis on Chinese Patents in Carbon Fibers Industry

首先从整体把握该产业的布局,简要介绍了碳纤维的国内外发展历程,并绘制了碳纤维产业链图。又进一步利用专利分析的方法,对碳纤维产业中国专利公开申请量、主IPC分布、主要专利权人等因素展开分析,研究其技术研发趋势、技术侧重点、主要竞争者实力和研发独立性等方面。结果表明,我国碳纤维产业正处于发展期,虽已取得技术突破,但与国际先进水平仍存在一定的差距。该领域的关键技术被日本、美国等跨国公司所掌控。因此,为了推进碳纤维产业的快速发展,国内在发展战略部署和技术掌控方面仍需改进。

Firstly, through literature survey, the development process of carbon fiber was described, and the industrial chain of carbon fi- ber industry was drawn out. Then, based on the data and tool of patent analysis, main IPC distribution and main assignees, the develop- ment trend of main competitors, R＆D capability, technical focus and innovation ability were also analyzed. The competitiveness of indus- try＇s main assignees and the development of carbon fiber industry in China were explored lastly. The results show that the carbon fiber in China is in its development period, with the technology breakthroughs achieved, there also exist gaps with the international advanced lev- el. The key technologies in this field has been controlled by multi-national corporations of Japan, the U. S. , etc.. To promote the rapid development of domestic carbon fiber industry, the strategic plan and technical control still need to be improved.
