The Effects of Processing Parameters on the Mechanical Properties of Aluminum-Graphite Composites.
Abstract
Aluminum-graphite composites are produced through molten infiltration of aluminum into continuous tows of graphite fibers by means of a process developed by The Aerospace Corporation. This process produces a continuous rod of composite that is subsequently fabricated into larger structures. This fabrication step involves hot-pressing of the wires in temperature ranges where the matrix is fully solid, fully liquid, or partially liquid and solid. The influence of the temperature region of fabrication on the final mechanical properties is discussed. The effects of cleaning of the precursor rod on the bonding of this composite are demonstrated. Fracture analysis with scanning electron microscopy is used to demonstrate the role of pressing parameters on the fracture process and the resulting mechanical properties.
