Hyosung High tech Materials has developed ultra-high strength carbon fiber, which is a step closer to the localization of aerospace materials.
Hyosung said on October 12 that it had successfully developed a "H3065 (T-1000)" ultra-high strength carbon fiber with a tensile strength of 6.4 GPa and an elastic modulus of 295 GPa or more.
It can be used in aerospace, aviation, national defense and other fields… It is a necessary material developed in the aerospace industry
The strength of "H2550 (tensile strength 5.5 GPa, elastic modulus 250 GPa, T-700 grade)" carbon fiber, which Hyosung has been committed to producing, is more than 10 times that of steel
It is mainly used for hydrogen fuel tank, wire core materials, solar insulation materials, sports and other purposes. In contrast, the "H3065" carbon fiber developed this time is a special carbon fiber with ultra-high strength, which is more than 14 times stronger than steel.
In particular, ultra-high strength carbon fiber is considered as a necessary material for the development of aviation launch vehicles and satellites in the aviation industry.
Compared with the existing materials such as aluminum used in launch vehicles, this material is much lighter, and has higher elasticity and strength, so it can minimize the weight of launch vehicles, and can withstand high loads and improve propulsion.
At the same time, the advantage of carbon fiber carrier rocket is that it can carry less fuel by reducing weight, so it can increase the weight of carrier.
In addition, in the field of national defense, when carbon fiber is used on the launcher, the weight can be minimized, so as to obtain the effect of improving speed and range.
T-1000 carbon fiber requires high difficulty in overall engineering, such as raw material polymerization, spinning and firing, and requires differentiated technologies.
In addition, this achievement has made Hyosung High tech New Materials evaluated as ensuring its competitiveness in the new favorite carbon fiber industry.
Hyosung will be able to enter the aerospace carbon fiber market with high added value by developing "H3065" carbon fiber.
Aerospace carbon fiber occupies the second place in the global carbon fiber market with 15% of the total amount, but accounts for more than 30% of the total amount. It is a high value-added market. Hyosung plans to complete the follow-up application research in the shortest time through cooperation with institutions.
In addition, Hyosung first developed the "high-performance carbon fiber TANSOME" in South Korea in 2011 based on its own technology ®”， The factory in Quanzhou has been operating since 2013.
Hyosung plans to invest 1 trillion won by 2028 to expand its carbon fiber production line to 24000 tons per year. In order to increase the current production capacity from 6500 tons to 9000 tons per year, it is adding for the third time.
