Incorporation of composite materials in cryogenic propellant tanks can potentially aid in developing high performance rockets. This study thus evaluates various aspects of carbon fiber reinforced epoxy laminates, such as elastic constants, failure strength, and development of internal damages, at cryogenic temperatures by employing a cryogenic testing system comprising a cryostat and a refrigerator. Test results obtained at cryogenic temperatures were compared with those at the room temperature for studying the effect of liquefied propellant's cryogenic temperature on the fundamental mechanical properties of composite materials. The obtained results indicate that compared to the room temperature, the damage initiation stress and failure strength of the composite laminates at cryogenic temperatures can decrease significantly, whereas the stiffness of the composite laminates at cryogenic temperatures can increase marginally. Furthermore, this study report also describes a method for temperature control through a heater system, and a method for stress measurement at cryogenic temperatures using the cryogenic testing system with the help of a refrigerator.
