Natural fiber composites are the composites in which fibers and plastics are used to reduce the cost of plastic raw material. So in the present study, a rice husk polypropylene composites were used by varying the volumes of filler material as rice husk and also varying the additives that are talc powder, mica powder and calcium carbonate powder. With the variation of volume nine samples of different composition were designed. Through the Minitab 16 software, various design and graphs are plotted to check the Mechanical properties, Flexural strength and Impact Strength of the material sheets and improved with reinforcement.
