| Abstract Scope |
Aluminum carbon fiber composites (Al-CF) have tremendous theoretical potential that is currently being hindered by critical technological challenges. Central among these are difficulties in forming low-defect density interfaces exhibiting robust metallurgical bonding. In their current form, Al-CF interfaces often show defects and lack robust mechanical interfaces that can transfer significant stress between the constituents. This leads to the physical properties of the composite being far below their theoretical potential and, often, inferior to the unreinforced matrix.
This work describes innovative strategies and techniques to overcome these interface-related challenges, thereby harnessing the full potential of Al-CF composites. We manipulate the interface via processes like intermetallic phase formation to bolster interfacial adhesion and load transfer capacity. By controlling the microstructural evolution during manufacturing, our technology creates interfacial phases that ensure distributed load sharing between the composite's constituents, mitigating the risk of localized stress concentrations and potential material failure. |
