Damping characteristics of Zn-Al matrix composites
- Shanghai Jiao Tong Univ. (China). State Key Lab. of Metal Matrix Composite Materials
Among high damping materials, Zn-Al alloys are considered to be the most excellent non-ferromagnetic damping alloys due to their attractive properties such as low melting point, low density, good workability and high damping capacity in a broad frequency range. The limitations to high temperature use of these alloys are their poor high temperature mechanical properties and dimensional instability. Recently, various reinforcements have been added to Zn-Al alloys to improve their high temperature properties while to increase their specific strength. Stiffness, wear resistance and to decrease thermal expansion coefficient. However, the effects of these reinforcements on damping behavior of Zn-Al alloys are yet to be elucidated. The present paper is to report some new phenomena found in preliminary damping studies of long graphite fiber, short graphite fiber and silicon carbide whisker reinforced Zn-Al alloy based composites.
