Strength Analysis of Particle Reinforced Epoxy Resin Composite Materials by Experimentation

Composite materials are made of two or more constituent material with significantly different physical or chemical properties that when combined produces a material with different characteristics than its constituents. Present work deals with study of tensile and flexural strength of polymer matrix composite material reinforced with titanium dioxide (TiO2) and tungsten carbide (WC) particles. Test specimens were prepared by reinforcing TiO2 and WC particles at three different weight percentage (15%, 20% and 25%). Test specimens were prepared by casting technology in wooden moulds. Tensile and flexural tests were performed on universal testing machine. All tests were performed as per the ASTM standards. From test results it was found that tensile and flexural strength of specimen goes on increasing with addition of WC particles. Tensile strength decreases for TiO2 reinforced composite specimens.
