Abstract: Polymers reinforced with synthetic fibers such as glass, polyester, acrylic, nylon, rayon, acetate, orlon, Kevlar bear high mechanical properties compared to natural fibres, but their adverse effects, such as peak initial costs, chemical reactivity with other materials and not suitable for some (non-efficient) structural forms, reduce demand. We are now switching gears from synthetic to natural fibers as the natural fibers are being overplayed over synthetic fibres. Here we focus primarily on testing mechanical properties such as tensile and bending. The specimens must be cut in accordance with the dimensions specified by the ASTM machine standards. The material properties and variation of the materials can be studied by changing the percentage volume composition of the fiber to the resin. The weighted ratios are taken as 40:60, 30:70, 20:80, 10:90 as the basis for making a composite. In the present work, we use the 235 * 165 * 5 dimensional mold in mm with natural fiber for reinforcement as a Palmyra fiber. To make the composite, the other materials such as Epoxy Resin(LY556) and hardener(HY951) must be added. Resin may also be called PMC(Polymer Matrix Composite). It is possible to resolve the tensile and bending properties of various composites and to draw a comparison of properties between the composites.
