“First in Korea to Manufacture Space Launch Vehicle Composite Tanks”
Using purely domestic technology in composite manufacturing and space sector business, our space launch vehicle composite propellant tanks, developed with our proprietary pure composite manufacturing method, achieved a weight reduction of approximately 23% compared to traditional metal tanks. We have completed cryogenic tests, flight load tests, and permeation tests, thereby owning the critical technology to reduce the weight of existing launch vehicles and secure additional payload capacity.
Scope of Maintenance Capability
· TYPE - V Linerless, Carbon Fiber Composite Propellant Tanks
· Over 30% reduction in weight and manufacturing costs compared to traditional metal propellant tanks
· Secured structural safety against extremely low temperatures and flight loads.
