Company with Experience Manufacturing Fairings and Structures for Naro and Nuri Rockets

Glass Fiber Manhole Impact Resistance 4 Times That of Cast-in-Place Manholes

Rail Vehicles Require High Reliability; Supplies Cockpits, Lavatories, etc.

Amid continuous efforts toward carbon neutrality across all industries, Hankuk Fiber is accelerating the expansion of its heavy industries leveraging chemical fibers. Particular attention is focused on the company's widening scope in fields demanding advanced technology.

According to industry sources on the 31st, Hankuk Fiber is pursuing various businesses primarily through three divisions—Glass Fiber, Rail Vehicle Components, and Aerospace—riding the wave of carbon neutrality.

Established in April 1972, the company was designated as a defense contractor in May 1978 and received aviation material certification from the US aircraft manufacturer Boeing in February 1992. Hankuk Fiber is indeed recognized for leading the advancement and globalization of the defense industry by utilizing its composite material know-how across land, sea, and air applications.

Hankuk Fiber produces the nozzle internal materials for the K-31 Chunma, a self-propelled anti-aircraft missile system deployed in 1999 and still operated by the Army. The company's materials are also applied to significant parts of Navy vessels, including the battery cases, H2 cylinder covers, PRS sonar domes, and rudders for the KSS Jangbogo II submarine.

Hankuk Fiber manufactured the fairings and composite structures for South Korea's first space launch vehicles, the Naro rocket and the Nuri rocket. The cockpit bucket for Korea Aerospace Industries (KAI)'s utility helicopter, Surion (KUH-1), is also supplied by Hankuk Fiber.

Currently, Hankuk Fiber is undertaking key development projects utilizing carbon materials.

The company also stands out in the construction materials sector through its glass fiber technology.

The features of the glass fiber composite pipes include: △ high rigidity, △ high elasticity, △ high water permeability, △ water tightness, △ water tight stability, △ semi-permanent lifespan, △ eco-friendliness, △ ease of construction, △ temperature change stability, △ seismic stability, and △ corrosion resistance stability.

Additionally, manholes produced with this technology have the advantage of being lightweight, shortening construction time, and achieving cost savings. Their compression strength is also about four times higher than conventional cast-in-place manholes, resulting in excellent impact resistance.

This high level of reliability is also required in the railway sector, where operational safety is paramount. Rail vehicle components must meet conditions of high strength, flame retardancy, and lightweight properties.

Hankuk Fiber satisfies all these conditions and supplies rail vehicle interior and exterior materials made from glass fiber composites to companies like Hyundai Rotem.

Products from Hankuk Fiber, such as the driver's cab, passenger cabin, auxiliary rooms, and lavatory modules for the KTX-Sancheon operated by Korail, are also the company's products.
