A Study on Mechanical Properties of Symmetrical and Asymmetrical Woven Jute Fiber Composite Polymer

Practice of biodegradable composites increase the attraction due to its lightweight and adequate strength. These plant fiber reinforced composites have captured the attention in construction and automotive industries. Jute fiber is one of the most affordable natural fibers obtained from the genus corchorus plant. In the present article woven jute fiber reinforced polymer composites are analysed to achieve the optimum layers and orientation of fibers for their peak mechanical properties. This study deals with the analysis of symmetrical and asymmetrical woven jute fiber reinforced polymers composite. Different types of composite test coupons are prepared based on number of layers and orientation of fibers like 0°, 15°, 30°, 45°, 60°, 75° & 90°. Polyester resin and Methyl Ethyl Ketone Peroxide is used as a matrix and catalyst respectively. Tensile and flexural strength properties are studied as per respective ASTM norms. The woven jute fiber composites with different orientation exhibits better mechanical properties than randomly oriented fibers. Tensile and flexural tests are conducted and the results are tabulated. It was also found that as the number of layers and orientation angle increases the strength's and modulus of composites are decreased.
