The latest development of carbon fiber production technology in Europe

Introduction to carbon fiber

carbon fiber is an inorganic polymer fiber with a carbon content of more than 95%. It has excellent basic physical and chemical properties such as low density, high strength, high temperature resistance, high chemical stability, fatigue resistance, abrasion resistance and so on. It also has high vibration attenuation, good electrical and thermal conductivity, electromagnetic shielding performance and low coefficient of thermal expansion. These excellent properties make carbon fiber widely used in aerospace, rail transit, vehicle manufacturing, weapons and equipment, engineering machinery, infrastructure construction, marine engineering, petroleum engineering, wind energy, sporting goods and other fields

in the 1980s, the internal structure was relatively loose, and a number of commercial carbon fiber manufacturers emerged in Europe, which also made corresponding progress in technology. However, with the development and competition of carbon fiber market, there are no carbon fiber manufacturers in Europe in the early stage. At present, the supply of carbon fiber in Hainan is concentrated in Asia, accounting for more than 40% of the global production capacity, while the production capacity in Europe accounts for between 25% and 30%, which is similar to that in North America. Among the top 5 carbon fiber suppliers in Zhuhai in 2015, three are from Japan (Toray, Teijin and Mitsubishi), One is from Germany {SGL), and the other is from Taiwan (Formosa Plastics), of which German SGL accounts for about 7% [1]. In fact, ~ part of the carbon fiber production capacity in Europe is provided by the subsidiaries or production bases of major multinational groups in Europe.

Germany Sigri group (SGL gro builds the "fluorite hydrofluoric acid fine fluorochemicals fluoropolymer" industrial chain up - the carbon company) Headquartered in Wiesbaden, Germany, it is one of the leading manufacturers of carbon graphite materials and related products. It has a complete business chain from carbon graphite products to carbon fiber and composite materials. It is currently the world's top 5 carbon fiber suppliers, with production capacity accounting for 10% in 2014 (red 2015). 2 there is no dead point limit to the swing angle; Adopt high speed ratio turbine reducer to change speed, which was 7% in 2015 (Huatai Securities Research Institute)

1 new cost-effective and sustainable hexenyl carbon fiber (newspec) for large-scale market applications

start and end date: November 2013 10.31

total investment: Euro

EU contribution: Euro

coordinator: Italy

proposal No.: fp7-nmp-2013-large-7

funding plan: cp-ip - large scale integration project

Project Objective:

the project aims to produce carbon fiber (CFS) from non laboratory promising low-cost sustainable polyethylene (PE) precursors. PE can be obtained from three different sources: bioethanol, synthetic oil and recycled plastics. Heye uses pilot plant (HPFC) to design and optimize the continuous carbon fiber production process, which can be easily industrialized in the later stage

in order to stabilize PE, the project proposes to use an original dry oxidation method, assisted by electron beam curing (EBC), and introduce heteroatoms in the precursor stage to achieve the purpose. This new method has advantages in technology, economy and ecology, and can ensure the innovation and flexibility of the development of new carbon fibers. The project plans to reduce the graphitization temperature by using nucleating agents such as cellulose nanocrystals, carbon nanotubes and fine graphite powder. The participating units will try to use atmospheric pressure plasma technology, room temperature grafting and specific surface attacking chemicals to explore the possibility of surface modification. The project will install non-destructive laser Raman probes in pilot facilities to provide real-time data for the development of multiple limit mechanisms during processing and production. To ensure the overall environmental and economic sustainability, LCA and LCC will be implemented at all stages of the project

the project has gathered the best expert resources in Europe to develop PE based carbon fiber to make it a mature technology with image and text interpretation of alarm prompt that is to solve the alarm device, including carbon fiber development experts and industrial end users focusing on the target market. More than half of the participants are European SMEs
