Abstract
Zyvex in cooperation with Prairie View A&M (CARR) and Boeing will develop a space radiation shielding multi-functional material that will provide high energy radiation shielding required to protect astronauts on extended missions, strong enough to be used as an integral structural material and tough enough to survive micro-meteor impacts, provide EMI shielding, and enhanced thermal conductivity. The team will also develop an improved protocol for testing radiation shielding material. This effort will entail developing a composite material which uses proven radiation shielding material Polyethylene(PE), as its primary constituent in the form of very strong/tough Spectra fibers woven into a 3D fabric. In Phase 1 we demonstrated that, compared to bulk PE, this composite approach has significantly improved mechanical properties, excellent electrical conductivity, good Electro Magnetic Interference (EMI) shielding properties, and maintains excellent space radiation shielding properties of PE. We also demonstrated exposure to large doses of high energy actually improved the mechanical properties. In Phase II, the epoxy matrix used in Phase I will be considered along with Cyanate Esters, and Polyimides, As in Phase I, coating the PE fabric and reinforcing the matrix material will be ultra-high strength, highly conductive carbon nanotubes (CNTs). Zyvex's unique and commercially successful CNT processing technology will be adapted to maximize the transfer of the extraordinary mechanic
