Aramid fiber is known as "super fiber," or "golden silk," because even though its weight is equivalent to only 20% of the weight of steel, it is more than five times as strong and does not burn, even at 500°C. Aramid fiber is an essential material used in various applications such as body armor, fire-resistant clothing, fiber optic cable reinforcement, high-performance tires, and aerospace materials. The late Dr. Han-Sik Yun began researching aramid fiber at the Korea Institute of Science and Technology (KIST) in 1979 and secured independent source technology in 1984.
