Summary

A Sic coated graphite fiber/aluminum composite was processed by plasma enhanced chemical vapor deposition (PECVD) of silicon carbide followed by the aluminum pressure infiltration. Miniature tensile specimens were tested in situ in the high voltage electron microscope at the NCEM. Preliminary studies showed that fracture in the Sic coated graphite fiber/aluminum composite advances by decohesion of the graphite fiber/amorphous Sic interface. These studies on deformation and fracture will serve, in addition to providing data on interface composition and structure, as a basis for modeling interface properties.
