Carbon Fiber Products

Carbon fiber that expands possibilities  Carbon fiber is produced by heat-treating special organic fiber and graphitizing it. Carbon fiber, on top of carbon's various characteristics, has flexibility because of its fiber shape. Therefore, carbon fiber is used in a wide range of fields such as aviation, space, electronics, automobile, and energy industry.
