A mega production base for T1000 carbon fibre is launched in China

-

A high-performance #carbonfibre project in Datong, North China’s Shanxi Province, was completed and put into operation. The 200-metric-tonne-per-year demonstration line, which achieves domestic mass production of 12K small-tow T1000 carbon fibre, began construction in June 2024. It represents the first phase of the 1,000-tonne high-performance carbon fibre project led by Shanxi Huayang Carbon Material Technology (Huayang Carbon), a company jointly established in 2023 by #Huayang New Material Technology Group, the Datong city government and the Institute of Coal Chemistry under the Chinese Academy of Sciences.


According to Huayang Carbon, the #T1000 carbon fibre produced by the project has a single filament diameter of only 6 to 7 micrometres less than one-tenth the width of a human hair but with a tensile strength exceeding 6,400 MPa. Its density is only one-quarter that of steel, yet it is more than five times as strong.


A 1-metre-long strand weighs just 0.5 grammes but can carry a load of 200 kilograms. It is resistant to high temperatures and corrosion, remains chemically inert in acidic and alkaline environments and has excellent thermal and electrical conductivity.


Advanced technologies in the coal mining region of northern China

A key pillar of China’s strategic emerging industries, high performance carbon fibre is useful in national #defence, #aerospace, #railtransportation and the fast-growing low-altitude economy. It is also used in wind turbine blades and sports equipment, according to experts.


Cao Rongxiang, deputy secretary-general of the Shanxi provincial government, told Chinese media: “The project has not only achieved a breakthrough in core high-performance carbon fibre technology, but also filled an industrial gap in the province.

#China is already a major global producer of carbon fibre, but it long faced a bottleneck in scaling up production of high-quality grades. The Datong project represents a key step in overcoming this challenge


As domestic manufacturers continue to overcome technical barriers and ramp up production, carbon fibre costs will fall sharply, Xiang Ligang said. That will open the door to far broader adoption, such as in shipbuilding, transportation equipment, vehicle components and unmanned logistics vehicles, reshaping the foundations of multiple industries, in particular emerging technologies.


Another Chinese company has also developed technology for the mass production of T1000 grade carbon fibre: in 2023, the “ultra-high-strength #ZA60XC (T1000 grade) #PAN carbon fibre 1,000-tonne industrial production technology” completed by Changsheng Technology, based in Hebei province, and Shenzhen University through collaborative technical research, passed the appraisal of scientific and technological achievements.

Today's KNOWLEDGE Share What Is Going Wrong in UK Plastics Recycling? Biffa shut its Sunderland plant. Viridor walked away from Avonmouth and Rochester. Yes Recycling Fife collapsed within a year. All three were backed by major investments All three had buyers lined up for recyclate All three are now offline This is not bad luck It is bad structure Over the next four posts I will break down: 1. Why cheap virgin imports are undercutting UK recyclers 2. How weak policy enforcement is fuelling market failure 3. What volatile PRNs and cheap exports are doing to infrastructure 4. Why demand from brands is softer than their promises Let’s start with the first: **Cheap Virgin Resin = Broken Economics** Virgin PE, PP, and PET have been flooding the global market. New capacity in Asia and the US has driven prices down 30 to 40 percent. Meanwhile, recycled plastic costs more to produce in the UK than it can sell for. We are asking UK recyclers to compete with materials made in places with – ...

Today's KNOWLEDGE Share “Robotic 3D printing can compete with traditional boatbuilding”, Simone Barbera and Mattia De Santis, Caracol V2 catamaran was printed in Italy at Caracol’s production center and headquarter in Barlassina, near Milan, with a Heron AM 400, Caracol’s robotic Large Format Additive Manufacturing (LFAM) platform. The lattest was specifically configured with a 7-axis robotic arm mounted on a rail, enabling the printing of parts up to 10 meters in length. How did the collaboration between V2 Group and Caracol come about? Simone Barbera : The collaboration between V2 Group and Caracol originated from a shared vision to revolutionize boat manufacturing through sustainable innovation. V2 Group, a Spanish-company specialized in nautical design and engineering, is seeking to develop electric vessels manufactured sustainably. On the other hand, Caracol, leader in robotic advanced manufacturing technology, had had years of experience working with Large Format Additive Ma...
