Carbon Fiber

Carbon fiber for Better World
The 21st century has required structural designers to reduce weight and conserve energy. This has resulted in carbon fiber composites as the primary material solution of choice due to the extraordinary material properties carbon fibers offer. Market applications for Carbon Fiber include aerospace, industrial, marine, automotive and sport/leisure goods.

Carbon Fiber material properties are achieved by spinning and stretching a highly engineered acrylic fiber (precursor) and then carbonizing this fiber at extreme temperatures. High performance carbon fibers include: "High Strength" grade tensile strength of 4.9 GPa (710KSI) and tensile modulus of 250 GPa (36.5MSI) "Intermediate Modulus" grade tensile strength of 5.5 GPa (800KSI) and tensile modulus 290 GPa (42MSI). These fiber types account for over 70% of the total worldwide market demand.

To satisfy the increasing demand for carbon fiber that is forecasted to grow by 10% - 15% per year, Hyosung will be increasing annual production capacity of carbon fiber for High Strength and Intermediate Modulus fibers by an additional 2,000 MT at the start of 2013. Hyosung plans to grow and become a Leading manufacturer in carbon fiber production by 2020. During this time Hyosung research and development will build upon their existing fiber technology in order to bring new carbon fiber products to meet the needs of their customers.
