Radiation effects are one of the main challenges for electronic components operating in space. The primary objective of the SRPROTEC project is to develop and validate composite materials that provide radiation shielding and preserve the microelectronics used in space applications. To achieve this, we will integrate elements typically found in shielding materials into a polymer matrix, seeking synergistic effects that enhance overall material performance.
The use of composite materials in space is a promising approach. Current trends focus on leveraging the properties of polymers to create lightweight materials that are radiation‑resistant and offer insulation capabilities. Their direct application lies in semiconductor encapsulation, using plastic materials in commercial off‑the‑shelf (COTS) components. This could have a direct impact on satellite efficiency by reducing mass and volume while improving functional reliability through reduced degradation caused by radiation effects.
This project is a collaboration between ALTER and the Technological Center for Components Foundation (CTC), within the framework of the 2021 Public‑Private Collaboration Projects Call of the Spanish Ministry of Science and Innovation. The call is co‑funded by the European Union through Next Generation EU, as part of the Recovery, Transformation and Resilience Plan presented by the Government of Spain.
