2022-08 Abstract Title: Durability Studies of Advanced Materials for deployment to Low Earth Orbit (LEO)

Abstract Body: There is an increasing need to protect and repair structural material systems deployed to Low Earth Orbit (LEO) from damage due to orbital debris impact and erosion due to the combination of atomic oxygen (AO) and UV radiation. This presentation focuses on ground-based simulated debris impact experiments and direct exposure experiments to AO+UV at the ISS of polydicyclopentadiene (PDCPD), modified PDCPD, and the corresponding nanocomposites, to evaluate the potential of this new class of 3D printable materials for deployment to LEO.
