Vibration Characterization of SiCp and Fly Ash Dispersion Strengthened Aluminium 5083 Composites

Abstract

The requirements of current day engineering applications is based on high damping materials which exhibit superior mechanical properties as well as high damping limit for vibrations. In structures made of metals and composites, it is difficult to achieve high damping limit and great mechanical properties at the same time. This is majorly due to the infinitesimal systems that result in "microscopic mechanisms and parameters affecting the mechanical strength". However, to accomplish a metal matrix composite system with unique properties of better mechanical properties as well as vibration characteristics; essential techniques involving the fabrication of hybrid composites with Aluminum 5083 as the base metal and Silicon carbide and fly ash as the reinforcement is considered. The composition of each of the reinforcements dispersed plays a particular part in affecting the damping characteristics or mechanical strength. In the current paper, the results of vibration tests carried out on hybrid Aluminium metal matrix composite plates as well as the results obtained from computational analysis using ANSYS software are interpreted to effectively determine the damping ratio, frequency, magnitude, phase angle and presented to understand the dynamic behavior of composite materials under the effect of different parameters.
