Abstract

The purpose of this study is to investigate fabrication condition of Al/Al{sub 2}O{sub 3}/C hybrid metal matrix composites and to characterize their mechanical and wear properties. Carbon and alumina short fibers reinforced hybrid MMCs are fabricated by squeeze infiltration method. Wear tests were carried out under various sliding speed conditions to identify wear behavior. Wear mechanism of MMCs is suggested by the examinations of worn surfaces. The effect of carbon fibers on wear resistance of Al/Al{sub 2}O{sub 3}/C hybrid metal matrix composites are discussed.
