Small Filament Wound Lightweight Missile Defense Interceptor Shielding Structures

In this MDA program, NanoSonic proposed to combine our structural component composite additive manufacturing (AM) technology with our Thoraeus Rubber veil to produce ultra-lightweight electronic and radiation shielding composites for missile interceptors. NanoSonic has recently developed ultra-high temperature and shock resistant 5" diameter gun barrel overwraps our AM filament winding process. These innovative carbon fiber reinforced polymer (CFRP) armament casings are wound with IM7 carbon fiber at room temperature with high performance HybridSil poly(organosiloxane-imide) thermoset resins, unique to NanoSonic. We have also recently demonstrated new Thoraeus Rubber composite constituents that offer EMI shielding up to -105 dB (2 - 20 GHz) and durability upon simulated space radiation exposure (1GeV proton, 27 Gy and 1 GeV Fe, 27 Gy). In Phase I, NanoSonic shall develop ultra-lightweight shielding composites up to 10" in diameter based on advanced materials for mechanical, shock, vibration, and radiation durability studies to achieve TRL 5. The new lightweight shielding structural components shall be tested alongside state-of-the-art missile interceptor materials to achieve TRL 7. Lockheed Martin Missiles and Fire Control (LM MFC) shall serve as our technology transition partner to identify and down-select composites for advanced missile systems in support of their Targets and Countermeasures Program.
