Recently, the applications of composite materials to the cryogenic propellant tank structures are under consideration to improve performance of rockets. It is necessary to clarify effects of cryogenic environment of liquefied propellant on the characteristics of the composite materials for the propellant tank application. Biaxial mechanical properties of the composite materials are also important for the tank structure subjected to internal pressure and structural loading in addition to the thermal loading at cryogenic temperature. In Aeronautical Technology Directorate, Japan Aerospace Exploration Agency, biaxial mechanical properties of materials had been evaluated with a biaxial fatigue testing machine at room temperature until now. For the purpose of cryogenic biaxial evaluation of the composite materials, a cryogenic environmental chamber has been newly developed. This report summarizes the development of a cryogenic environmental chamber for biaxial mechanical property testing. The cryogenic environmental chamber that a cruciform specimen could be applied biaxial load under cryogenic temperature was designed based on the findings summarized in the previous report. In this report, experimental procedure and results of performance tests are also summarized.
