Hyosung Advanced Materials (Seoul, South Korea) announced in October 2022 that it succeeded in the development of ultra-high-tensile carbon fiber H3065 (T-1000 class), which is reported to have a tensile strength and elasticity of at least 6.4 GPa and 295 GPa, respectively.
Hyosung Advanced Materials has produced carbon fiber H2550 (tensile strength: 5.5 GPa/elasticity: 250 GPa, T-700 class), which is chiefly used in hydrogen fuel tanks, electric cable core, PV thermal insulation, sports, etc., as its tensile strength is 10 times that of steel. In contrast, the newly developed carbon fiber boasts tensile strength that is 14 times that of steel, and can be used in a variety of sectors such as aeronautics and defense to make airplane fuselage/parts and projectiles like satellites.
“The feat has made Korea the third country to develop ultra-high-tensile carbon fiber after the United States and Japan, and it will contribute greatly to the development of the country’s carbon fiber industry,” Hyosung chairman Cho Hyun-joon says. The company says this is because T-1000 class carbon fiber requires highly sophisticated technology concerning raw material polymerization, radiation, elasticity, etc.
Director Bang Yoon-hyuk of the Korea Carbon Industry Promotion Agency notes that the country has relied on imported materials for carbon fiber used in aeronautics, defense and future mobility. According to business observers, the feat means that Hyosung Advanced Materials has taken one step closer to its objective of ranking among the global top three in the carbon fiber sector and secured solid competitiveness in said sector, which it regards as a new sector that will provide continued growth and jobs.
According to the Fuji Economic Research Institute of Japan, the global PAN-based carbon fiber market is expected to post a 10% growth (annual average) from 85,790 tons in 2021 and reach about 327,430 tons by 2035. As for the use of carbon fiber in global markets, as of 2021, wind turbine blades (39%) topped the list, followed by aeronautic (15%) sports/leisure (12%) and vehicles (7%).

Hyosung Advanced Materials plans to wind up its follow-up research for application within the shortest period of time through cooperation with the relevant institutions.
In 2011, Hyosung Advanced Materials developed on its own Tansome, a high-performance carbon fiber, for the first time. The company has produced it in its factory in Jeonju, Korea, since 2013. Hyosung Advanced Materials plans to invest one trillion won to increase the production capacity of said factory to 24,000 tons a year by 2028. At present, it is carrying out phase 3 of this expansion (from 6,500 tons to 9,000 tons a year).
Compared to legacy materials like steel, aluminum, iron and titanium, composites are still coming of age, and only just now are being better understood by design and manufacturing engineers. However, composites’ physical properties — combined with unbeatable light weight — make them undeniably attractive.
The matrix binds the fiber reinforcement, gives the composite component its shape and determines its surface quality. A composite matrix may be a polymer, ceramic, metal or carbon. Here’s a guide to selection.
As the wind energy market continues to grow, competition heats up between glass and carbon fiber composites for turbine blades.
