Improvement in Mechanical Properties by using Two Different Polymer Matrix Composites Reinforced with Carbon Flakes

Polymer Matrix Composite which contains two different resins they are epoxy and polyester resin reinforced with carbon flakes separately by using Innovative Method. High intensity ultrasonicator is used to obtain homogeneous mixture of epoxy resin, hardener with Carbon Flakes and also polyester resin, accelerator and catalyst with Carbon Flakes. The Hot Press Molding technique is used to create composite specimens. Tensile test, flexural test and impact test are performed on different weight ratios i.e., 5wt. %, 10wt.%, 15wt% and 20wt.%, of carbon flakes is reinforced with epoxy and also same weight ratios of carbon flakes reinforced with polyester resin is used to improve the reinforcement effect of composites. Bending strength, tensile strength and impact strength evaluated to represent the behavior of composite structures with flake load. The mechanical properties of composite are measured with help of UTM machine. The tensile test results indicate that the 5wt. % carbon flakes are reinforced with epoxy resin composites possesses the highest tensile strength and the tensile test results indicate that the 10wt. % carbon flakes are reinforced with polyester resin composites possesses the highest tensile strength. As compared to these mixture of carbon flakes are reinforced with polyester resin composites possesses the highest tensile strength.
