MEMBRANES AND MATERIALS FOR ENERGY EFFICIENCY Subtopic: High Performance Conductors "Reinforced Commercial Metals for Enhanced Electrical and Thermal Conductivity"

Major improvements in the electrical and thermal conductivity of metals used in conductors are needed to improve the energy efficiency and reliability of our national electrical power systems. These metals need to be stronger and more resistant to corrosion, oxidation and fatigue which reduce the reliability and lifespan of conductors and create high costs for maintenance, repair and replacement. Stronger aluminum and higher conductivity metals could dramatically decrease the amount of electricity lost in line transmission over long distances. Higher thermal conductivity can improve the load capacity of transmission lines and avoid damage caused by overheating. More efficient conductors can reduce the weight of wiring used in aircraft and motor vehicles, improving their load carrying capacity while saving fuel. These improved metals can also be used in heat exchangers making them more efficient, and lower overall demand for additional power generation even as our national consumption of electricity continues to increase. In Phase I, Advanced Ceramic Fibers propose to demonstrate the feasibility of using innovative, low cost, fiber- reinforced metal matrix composites to dramatically improve the strength, weight, system-life and conductivity of aluminum and steel used in a variety of power generation, transmission and distribution system components. This study will demonstrate, test, and report on various types of novel cast, extruded or forged fiber reinforced metal matrix composites to improve conductor strength, electrical and thermal conductivity, and reduce (or nearly eliminate) creep and permanent elastic deformation. Phase II and III will provide platforms for designing, fabricating, and testing specific components which may include High Voltage Transmission Conductors, conductor connectors, dead ends, heat exchangers and potentially, armor to protect distribution control centers and other critical utility structures. This same metal technology can be utilized in a wide variety of commercial applications to lightweight and strengthen metals used in aircraft and motor vehicles, building materials and nuclear power system components to name a few. The public will benefit from lower electricity rates and greater reliability of the electrical grid, including reduced maintenance, repair, and replacement of transmission lines and fewer costly and dangerous blackouts. Use of these metal composites can lightweight vehicles and aircraft improving load carrying capacity, improving fuel efficiency, and reducing harmful emissions. Aging infrastructure and increasing demands on electric power transmission and distribution systems underscore the need for more efficiency. A promising solution is the development of fiber reinforced metal composites that make transmission lines and components stronger and longer lasting, while also dramatically increasing the electrical load carrying capacity and reducing line losses.
