Linerless CFRP oxygen tank for space applications passes hydrostatic burst test

HyImpulse, Technologies in partnership with Greek advanced composite manufacturer, Adamant Composites, announced the successful completion of a hydrostatic burst test of a ground-breaking linerless Carbon Fibre Reinforced Polymer (CFRP) liquid oxygen (LOX) tank. This marks a key milestone in the development of HyImpulse’s orbital Small Launcher SL1. HyImpulse is a launch services provider based in Baden-Württemberg, Germany. Adamant Composites is specializing in the development of advanced composites for aerospace, industrial  and  defence  applications.

The hydrostatic burst test is a critical step in the development of any pressure vessel and is used to ensure the safety and reliability of the tank under extreme conditions. The test subjects the tank to pressures far beyond what it is expected to experience in normal operation, to identify any potential weaknesses or failure points.

The linerless CFRP LOX tank passed the test with flying colors, demonstrating its ability to withstand pressures well beyond the limits of its intended use. This is a major achievement for the teams at HyImpulse and Adamant Composites, as the use of linerless CFRP tanks in space applications is relatively new in Europe and has not been extensively tested.

“The use of linerless CFRP in our LOX tanks significantly improves our performance and reduces weight and cost. This successful test brings us one step closer to bringing this innovative technology to SL1 and revolutionizing the space launch industry” said Mario Kobald, CEO of HyImpulse. “We believe that revolutionizing access to space passes through revolutionizing composites structures design and manufacturing” said Antonios Vavouliotis, CEO of Adamant Composites. “The unique full composites design provides 30 % mass savings, while the robotic inspired production process reduces the cycle time by 50% and cost by 25 %.”
