A key technology enabler for next generation EMI shielding applications is low loss, lightweight, flexible, conductive carbon nanotube (CNT) tape. The primary goal of this effort is to determine the optimal geometry for a CNT based EMI shield to provide equivalent shielding effectiveness of cable harnesses and other electronics on the V-22 Osprey, while maintaining a maximum weight savings. The approach will include both modeling and experimental data and testing. The modeling of the V-22 will identify key electronic areas of interest, while the experimental data will feed more accurate information into the models to take full advantage of the CNT materials EMI properties and weight savings. Material development and some testing will be carried out by Nanocomp and the modeling effort along with additional testing will be led by Electromagnetic Applications, Inc. (EMA).
Benefit: The EMI shielding solutions developed in this program could potentially replace the heavy SPC braiding currently used in cabling harnesses across multiple platforms and industries both for military and government applications. Possible benefits of using a CNT based shielding include increased fatigue resistance, reducing maintenance and failure due to fatigue and vibration damage, and saving significant weight. If successful, Nanocomp Technologies expects to be able to provide lightweight shielding solutions to the Navy, US DOD, and prime contractors for aerospace and other applications. Significant weight savings can be achieved with our CNT shielding, with the resulting benefits of increased payload capacity or longer loiter times.
