A propellant tank for spacecraft is usually made of titanium alloy, it would not demise during atmospheric re-entry of the LEO spacecraft and cause a risk to the ground. So, it is desirable that a propellant tank would demise. Since 2010, JAXA conducted research to develop an aluminum-lined, carbon composite overwrapped tank for reducing impact risk to the ground. In the early phase, it expected that the resin of CFRP would decomposed by aerodynamic heat and residual carbon fibers were blown away by the effect of airflow. However, JAXA started reevaluation of the survivability of this composite propellant tank when debris mitigation study in JAXA was reorganized at 2016. This year, we conducted arc wind tunnel tests of material samples which were cut off from the EM tank. We report test results and current reevaluation status.
