Radiation shielding is needed for extended stays beyond LEO. During this effort, a multifunctional composite is being developed as an integral part of a spacecraft or habitat to provide shielding against Galactic Cosmic Rays (GCRs) and secondary particles, enhanced structural integrity, and durability against overall space environment. During Phase 1, innovative fabrication methods have been developed to produce the radiation shielding composite. Mechanical testing showed that compared to traditional aerospace aluminum alloys significant enhancements in specific strength and stiffness were obtained. During Phase 2, the composite will be optimized and samples will be produced for inclusion on MISSE-FF missions.
