Hyosung Advanced Materials Corp.
Hyosung Advanced Materials Corp. emerged from Hyosung Group's diversified industrial conglomerate, founded in 1966 by Cho Hong-jai. The advanced materials unit focuses on high-performance fibers and composites, with the group's chaebol structure providing both capital and industrial off-take relationships. The company's product portfolio spans tire reinforcement cords, steel cords, and aramid fibers for automotive, aerospace, and construction. It operates carbon fiber production lines in Jeonju, South Korea, targeting 24,000 tons annual capacity by 2028. The company also produces polyketone yarns for marine and industrial applications. In 2024, it secured a supply agreement with a European hydrogen storage tank manufacturer for its carbon fiber pressure-vessel-grade material (per public record). Hyosung Advanced Materials operates manufacturing plants in South Korea, China, and the United States, employing over 5,000 people globally. The parent Hyosung Group spans chemicals, machinery, and IT, with combined annual revenue exceeding $15B. In 2025, the company announced plans to build a new carbon fiber plant in Vietnam to serve Southeast Asian supply chains (per public record). The company's structural differentiator lies in its vertically integrated position within Hyosung Group—it benefits from captive demand from group affiliates in tire manufacturing, heavy equipment, and chemical distribution. This gives it a stable revenue base while allowing it to invest long-cycle in capital-intensive carbon fiber capacity that independent composites firms might not sustain.
