Nanostructured Composites for Space-Bound Housings

In satellites designed to monitor nuclear explosions, current electromechanical housings are fabricated from aluminum, which is much heavier than composite materials. Because it costs approximately $10,000 per pound to put an object into space, weight is critical. However, even with the obvious weight advantage, composite materials are not used: their low strength and minimal conductivity render present-day composites unsuitable for electromagnetic interference (EMI) shielding. This project will develop carbon-nanotube-based composite materials with much higher thermal and electrical conductivity. With increased conductance and carbon nanotube strength, these advanced composites would be suitable for space-bound housing. Phase I will synthesize carbon nanotubes, combine them in a resin to be hardened, and test the materials for strength and conductance. Phase II will involve further refinement and upward scaling for an eventual space-bound housing structure.Commercial Applications and other Benefits as described by the awardee: Lightweight conductive composites would have obvious use in aviation, where weight is critical. In addition, nearly every fabrication industry seeks to reduce the mass of its products ¿ this new class of carbon nanotube composites would be highly sought
