Damping behavior of Al/SiCP multilayer composite manufactured by roll bonding
Highlights ► Stepwise functionally graded material was produced by hot roll bonding. ► Damping capacity was performed on multilayer composite. ► High damping capacity achieves by increasing the percentage of reinforcement and number of layers. ► The natural frequency enhances by increasing the percentage of reinforcement.
Abstract High damping materials comprising good mechanical properties as structural materials and high damping capacity for vibration loading are the best solutions for vibration problem. In current study, functionally graded material from composite sheets with different percentages of reinforcement was manufactured by hot rolling process. The damping behavior of base alloy composite including different percentages of SiC particles and Al/SiCP multilayer composite sheets was studied at room temperature conditions. The Al/SiCP composites were found to exhibit higher damping capacity compared to Al alloy. The damping capacity increased by increase in the percentage of reinforcement. Furthermore, Al/SiCP multilayer composite sheet provided higher damping capacity in comparison to Al alloy. Therefore, damping capacity enhanced by increasing the number of layers. The main source for damping behavior in composite materials is dislocation damping whereas in stepwise multilayer composite sheets, it comes from boundary conditions between layers.
