Abstract
The invention consists of radiation shielding materials for shielding in the most structurally robust combination against galactic cosmic radiation (GCR), neutrons, and solar energetic particles (SEP). Materials for vehicles, space structures, habitats, landers, rovers, and spacesuits must possess functional characteristics of radiation shielding, thermal protection, pressure resistance, and mechanical durability. The materials are tailored to offer the greatest shielding against GCR, neutrons, and SEP in the most structurally robust combination, also capable of shielding against micrometeoriod impact. The boron nitride nanotube (BNNT) is composed entirely of low Z atoms (boron and nitrogen). Some of the materials included in this invention are: boron nitride (BN) platelets, hot pressed BN, BNNT, BN particle containing resins, BN nanofiber containing resins, carbon fiber reinforced BN containing resins, BNNT containing resins, and hydrogenated BN and BNNT, hydrogen stored BN and BNNT, high hydrogen containing polymer or ceramic matrices, and a combination of these.
