Fundamental studies to enhance ampacity in carbon nanotube conductors
Abstract
ONR 2015 Research Opportunity: Naval Platform Power and Energy, SN 15-SN-0005 Project Abstract Abstract: The increased power demands in naval systems, expanding sources of power that now include renewables (PV, wind, etc.), and the need to reduce weight, increase flexibility, robustness, and ampacity of electrical conductors motivates research interest in power distribution using nanostructured conductors. The proposed basic science program is aimed at fabricating and studying pure carbon nanotube (CNT) and CNT-metal/graphene hybrid wires with high conductivity, ampacity, flexibility and reduced weight. Recent reports have demonstrated CNT wires with enhanced conductivities and ampacity on microscale structures, but the current objective is to fundamentally understand fabrication approaches, metal/graphene doping levels, and physical geometries on the electrical properties of practical, larger diameter CNT wires. The research efforts will include a series of designed experimental studies that investigate extrusion and densification approaches, the impact of conductor geometry, and graphene or metal doping concentration. In parallel, an electro-thermal model will be developed to gain insight regarding the physical mechanisms that control electrical transport and ultimately influence CNT wire impact on Navy applications.
