Wet hand layup technique was used for the preparation of composites. Mechanical tests were carried out for different weight percentage of fiber by varying the number of layers. Mechanical properties were analyzed as a function of wt%. The maximum tensile, flexural, impact and shear strength was observed on a composite designated as D. But the maximum tensile and flexural modulus values were identified in a composite designated as E. Experimental results were compared with theoretical results such as the rule of mixture and Bowyer and Bader model. Bowyer and Bader model was able to predict the strength and modulus of the composites better than the rule of the mixture model. The comparison between experimental and predicted values was also done by the student t test.

The fiber which serves as a reinforcement in reinforced plastics may be synthetic or natural. Past studies show that only synthetic fibers such as glass, carbon etc., have been used in fiber-reinforced plastics. Although glass and other synthetic fiber-reinforced plastics possess high specific strength, their fields of application are very limited because of their inherent higher cost of production. An attempt has been made to utilize the coir, as natural fiber abundantly available in India. Natural fibers are not only strong and lightweight but also relatively very cheap. The present work describes the development and characterization of a new set of natural fiber based polyester composites consisting of coir as reinforcement and epoxy resin. Coir composites are developed and their mechanical properties are evaluated, at five diff...
