(Seoul, South Korea) announced that it will be expanding PAN carbon fiber production by adding a third line of 2,500 tons/year at its Jeon-Ju production facility in South Korea. This additional annual capacity of 2,500 tons will bring annual total carbon fiber production to 6,500 tons by July 2022. In 2020 Hyosung Advanced Materials also added a second carbon fiber production line. According to the company, the driving force of this expansion is to meet the demand for carbon fiber used in industrial applications such as cable core, building infrastructure and, in particular, fuel tank cylinders for compressed natural gas (CNG) and hydrogen vehicles, which typically reach 350-700 bar (5,000-10,000 psi) operating pressure. Hyosung Advanced Materials believes that with its high-strength and high-strain carbon fibers, TANSOME, will play a key role in type III and type IV cylinder pressure vessels and their safe operation, and will become a go-to solution for highly pressurized fuel tank cylinder manufacturers.
