Multifunctional Metal RubberT Composite Structural Materials
Agency / Branch:
DOD / MDA
This SBIR program would develop multifunctional structural composite materials based on NanoSonic's Metal RubberT. The Metal RubberT composites would offer mechanical stiffness-to-weight comparable with conventional cross-ply laminate face sheet and structural composite materials, but also incorporate high electrical conductivity, broadband RF/EMI shielding, and uniform thermal conductivity typically not available in polymer matrix composite systems. Metal RubberT is a self-assembled nanocomposite material that combines conducting nanoclusters and advanced polymers into free-standing sheets. These materials would be combined as plies with high performance reinforcement fibers to create cross-ply laminate composites during Phase I. Prior work has demonstrated low mass density (<1g/cc), highly electrically conductive (10-6 ohm∙cm), and useful RF and microwave shielding properties for NanoSonic's Metal RubberT ply materials. During Phase I, NanoSonic would modify the chemistry of its current Metal RubberT materials to allow their consolidation into composite structural materials using normal processing routes. Multiple Metal RubberT composite structural test articles would be delivered and evaluated to determine RF/EMI, electrical conductivity, thermal uniformity, useable temperature range, UV degradation and outgassing properties. NanoSonic would work with a large aerospace prime contractor involved in multiple MDA platforms and systems to design multifunctional requirements into Metal RubberT composite performance, and evaluate properties of test articles.
