Damping Characteristics of Metal Matrix Composites.

Abstract

Metal matrix composite (MMC) with enhanced material damping can be potential structural materials to significantly improve the stability control and reliability of space structures. The objectives of the present investigation are: i) to identify the mechanism and source of damping in MMC (p55 Gr/6061 Al) by using in-situ characterization techniques; ii) to determine the role of microstructural parameters, e.g., fiber volume, fiber orientation and interfiber spacing, and iii) to define the role of fiber matrix interfaces.
