In the present era, Natural fibers are favored for the formation of composites due to their low density, high strength, biodegradability, easy production, low carbon foot, environment friendly nature in comparison of synthetic fibers. This Paper deals with NFRC made from natural fibers obtained from the plants of arid region of Western Rajasthan on which a few researchers are focusing. This paper discuss on the extraction process of fiber from the ber’s stems, manufacturing of composites by using epoxy resin & ber’s fibers then testing of its mechanical properties e.g. tensile strength, young modulus, yield strength , and percentage elongation. Six Sample were made having weight ratio - 0.1, 0.2, 0.3, 0.4, 0.45, & 0. 6. Dog bone samples were prepared according to the ASTM D638 (Type IV) standard. Tensile strength varies from 12.19 MPa to 25 MPa, while young modulus varies from 1.4GPa to 2.9GPa for different weight ratios. Yield strength varies from 10.77 MPa to 21.16 MPa. Percentage of Elongation varies from 1 to 3%. These results shows that ber’s stems can be used for fiber extraction to manufacture composites materials & for better mechanical properties minimum fiber volume fraction percentage is 13% and maximum fiber fraction is 31%.This data can be used further when optimum value of fiber volume fraction is required to form composites from ber’s fibers.
