Multifunctional composite-based structures

The multifunctional structure (MFS) design concept is used to design the structural elements of a spacecraft, placing most of the spacecraft's electronic components on its composite-panel walls. The approach, coupled with higher-density electronic packaging technology, substantially reduces the overall weight and volume of future nanosatellites. The MFS design, as compared to traditional design, eliminates chassis and cabling, reduces electronic enclosures and harness, maximizes functional elements/volume ratio for maximum integration, shortens thermal paths from the electronic components to the spacecraft radiators, enhances the heat radiation capability needed for the growing dissipation density, and robustness and reliability. The MFS concept is technically feasible and it is especially interesting in the case of small satellites, where the size is the driving requirement.
