Modeling space environment effects on novel nanocomposite materials for satellites using ESA’s SPENVIS

This work simulates nanocomposite materials based on high-performance polymer matrices with two-dimensional fillers (graphene, hexagonal-boron nitride), aimed at improving the performance of satellite components in space environments, in particular within the Large Deployable Reflector (LDR) Antennas for different missions (low-Earth orbit, geostationary orbit, planets like Moon or Mars) for radar, telecommunication or scientific objectives. Radiation shielding properties are evaluated using ESA SPENVIS system (GENT4). Results show that total ionizing dose (TID) depends on material density, chemical composition, and geometry. Comparison with data in the literature confirms the potential use of these nanocomposites in maintaining mechanical properties under typical radiation environments.
