Space radiation effects from galactic cosmic rays (GCRs), solar energetic particles (SEPs), and the trapped particles within the Van Allen belts, directly influence space systems. These forms of radiation can degrade device performance through mechanisms such as total ionizing dose (TID), single event effects (SEE), and displacement damage (DD), which could result in a range of malfunctions, from minor functional deviations to catastrophic failures, potentially jeopardizing a space mission.

Considering this, the main objective of the SRPROTEC project is to develop and validate new composite materials with better shielding performance against space radiation, so they can be used as packaging materials for electronic components. To achieve this, different epoxy-based composites filled with particles with high atomic number were synthetized and thoroughly characterized, subjecting the samples to a wide range of physical and radiation shielding tests, to determine their radiation shielding performance and their suitability for electronic packaging.
The best formulation was selected to encapsulate electronic components via Dam & Fill process, obtaining test vehicles that were assessed through a dedicated test campaign aimed at determining the quality of the test vehicles manufactured with the novel composites and the radiation shielding performance of the package. The webinar will provide an overview of the project scope, detailed methodology, key results, final conclusions and future work.
