This paper deals with the damping performance of Zn-Al/pearlite composites under vibration circumstance. In the experiment, a kind of Zn-Al based composites was produced with the vacuum-infiltration method. The internal friction Q-1 of the materials was measured with the device DTM-Ⅱ-X under resonance situation and the damping mechanism of the composites was analyzed. The test result indicates that the damping capacities of pearlite reinforced metal matrix composites are better than that of the metal matrix.
