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 Gr6061 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.
