Interface Character of Aluminum/Graphite Metal Matrix Composites.

Abstract

One of the problems limiting the application of the aluminum/graphite composites to structural applications is the poor transverse properties. This research program has as a primary purpose the understanding of the contributing factors that govern the transverse strength and methods to improve it. In order to develop a better understanding of the character of the aluminum/graphite interface, a series of experimental approaches have been used. The key approaches taken are: (1) Scanning Auger Electron Spectroscopy (SAM) of the fractured surface; (2) Auger Spectrum deconvolution techniques to evaluate bonding state; (3) X-ray Residual Stress Measurements; (4) TEM - Interface Phase Identification; and (5) Electronic characterization of the interface. The combined approaches are being used to separate out the many factors that may influence the interface strength.
