NASA intends to use composite materials for both fuel tankage and fuel feedlines on future generations of RLVs in an effort to reduce the overall vehicle weight, which increases the amount of payload that can be sent into orbit. The composite feedlines have been found to be vulnerable to bumping and impacts from dropped tools. Because composites dissipate impact energy through the formation of damage, it was necessary to determine if polymeric coating materials could be used to improve the composites resistance to impact. Furthermore, many polymeric materials continue to embrittle with time, so the effects of aging were studied. Finally, thermal cycling of the coated composite specimens was performed to simulate the conditions present in launch to landing cycles.
