Analysis of Hardness and Wear Rate of Polypropylene Based Polymeric Composite through Grey Relational Technique

Over the last years natural composite materials have been the dominant emerging materials over plastics, fibers and ceramics. The volume and number of applications of natural composite materials have grown steadily, penetrating and conquering new markets relentlessly. The composites should not be regarded simple as a combination of two materials. The interest in polymeric composite materials is rapidly growing both in terms of their industrial applications and fundamental research. They are renewable, cheap, completely or partially recyclable, and biodegradable. Their availability, renewability, low density, and price as well as satisfactory mechanical properties make them an attractive ecological usage for the manufacturing of composites. The research on the present work shows that we can successfully manufactured Polypropylene based composite, which are widely used in the industrial field, especially in automotive applications, due to their excellent mechanical properties and low cost. This research is directed towards obtaining the optimal values of mechanical properties of organic polymer composite material for different objectives. Though the primary objective was to minimize the cost of the composite, simulations were also performed to obtain specific desired properties of the composite (irrespective of the composite cost). The latter simulation results are useful optimization of mechanical properties during machining of composite material using grey relational method.
