Abstract
NanoSonic has demonstrated that Shape Memory Metal RubberTM (SM-MR) adaptive skins exhibit reconfigurable and durable RF properties. It is hypothesized that such morphing skins shall also exhibit durable radiation resistance upon morphing; a property that few, if any, flexible materials offer. Typical highly filled or metal evaporated nanocomposites crack and spall upon flexation, and cannot be repeatedly mechanically stretched without rupture after a few cyclic strains. SM-MR nanostructured morphing materials are based on self-assembled high z, dense, Au and Ag nanoparticles, rather than Pb. Our manufacturing process yields tough skins that can be repeatedly and severely mechanically morphed without loss of EMI shielding (-88dB). NanoSonic, together with Colorado State University, have demonstrated that SM-MR is up to 50% lighter in weight and provides greater gamma ray attenuation relative to commercial off-the-shelf shielding materials, without emitting harmful secondary radiation under a 137Cs source. During Phase I, radiation shielding would be verified for SM-MR during potential disparate space array morphed configurations to demonstrate durability, stowability, and reconfigurability for space tolerant structures with self-healing properties to reach TRL6. TRL8 and 9 shall be reached during Phase II and III with assistance from our space systems prime partner upon flight testing and integration.
