Abstract

The prime objective in performing the machining operations is to procure products with meticulous dimensions
and exceptional surface finish. This necessity can be fulfilled by the utilization of precision machine tools for
machining processes. The machine tool structure must be composed of materials possessing high damping and
high stiffness properties. Cast iron is being used as a structural material for its good damping properties. Granite
epoxy composite is an alternative material due to its better damping and static stiffness. In this study, the vibration
behavior and mechanical properties of granite epoxy composite are analyzed by using cast iron particulates as
filler material. The granite epoxy composite specimens are fabricated as per the ASTM standards by altering the
epoxy and granite percentages in composite mixture in addition to 5, 10, and 15% cast iron particulates as filler
material. The mechanical properties such as compressive, tensile, and flexural properties have been investigated.
Dynamic analysis is carried out to evaluate the damping behavior for various compositions of granite, epoxy, and
cast iron particles. The inclusion of cast iron as filler material affects both mechanical and damping properties
based on filler content, which has been presented.
