| Abstract Scope |
Aluminum graphene composites offer an exciting array of unique properties including high electrical conductivities and strengths as well as low densities. Of interest, these materials approach the electrical conductivity of copper alloys with a density reduction of over 70%. These materials open the opportunity to replace copper in buss bars and current carrying applications. This shift would create significant weight savings in the automotive industry allowing vehicles to consume less power and travel further. While these materials offer many benefits, they are difficult to manufacture using traditional methods. Here, carbons’ propensity to disassociate into the aluminum matrix destroys the graphene, eliminating the benefit. This project has demonstrated the utility of a new technology, resistance-based sintering, for creating aluminum–graphene composites. This presentation will provide an overview of the technology, as well as the electrical and microstructural characteristics of the created products. |
