Damping Characteristics of Metal Matrix Composites.

Abstract

Fiber reinforced metal matrix composites (MMC) are candidate structural materials for Large Space Structures because of their high specific stiffness, specific strength, and low coefficient of thermal expansion. In addition, MMC exhibits higher damping than structural alloys of aluminum or titanium, and the potential exists for designing MMC with predetermined damping, strength, and stiffness properties. In the present investigation P55/6061 Al composites with different fiber-fiber (consequently, fiber volume) spacing have been selected to study the damping characteristics.
