Influence of Resin Content and Cast Iron Powder Addition on Vibration Characteristics of Granite Epoxy Composites

Abstract

With the advent of high speed machining, to improve productivity, the dynamic performance of machine structures especially in precision machining becomes critical. Granite epoxy composite is a novel material being developed as an alternate material for precision machine tool beds. This composite consists of well-graded granite particles and Araldite resin with a suitable hardener for curing the mix at room temperature. Several distinct advantages like excellent damping properties, long term dimensional stability, less curing time leading to shortest lead time for manufacture, long term dimensional stability and lower production costs compared to conventional Cast iron beds can be derived from this composite. Objective of this study was to investigate experimentally effect of resin content on vibrational characteristics of granite epoxy composite.
