Damping Characteristics of Metal Matrix Composites

Abstract

In the present investigation of damping characteristics of metal matrix composites, the objectives were to: 1) Develop an understanding of energy dissipation mechanisms in Gr/Al composites, 2) Characterize fiber/matrix interface structure, 3) Define the role of interfaces in damping, and 4) Identify and evaluate potential high damping metal matrix composite. To accomplish these objectives, initially damping measurement techniques were established to obtain reproducible and reliable test data of Gr/Al composites. These data obtained at different frequency and strain amplitude levels, were analyzed to develop an understanding of damping mechanisms in Gr/Al composites.
