Study of Mechanical properties of Epoxy composites filled with Graphite & TiO2

Abstract

Epoxy Based Resin filled with Graphite particle & TiO2 particle were made by hand layup technique. Tensile strength, Flexural strength, Impact, hardness & density were determined as per ASTMD 256, ASTMD 792, and ASTMD 2240. Composite containing 3 wt % of graphite particle exhibits the optimum mechanical & wears performances. A further increase in the graphite content increases the specific wear rate & deteriorates the mechanical performance. The performance of composites can further be improved by adding TiO2 filler in polymer. The present work includes the processing & mechanical characterization of the composite. The experimental results showed that as TiO2 increases (upto 4 to 5 wt %) density, hardness, Tensile strength & Flexural strength also increases & Impact strength decreases after increase in TiO2. The systematic experimentation leads to determination of significant process parameters & material variables that predominantly influence the mechanical properties.
