Data set on Effect of Alkaline Treatment of Sisal Fiber on Mechanical property Reinforced Polyester Composite

The fibers reinforced polymer composites (FRPCs) are developed primarily using synthetic fibers. Currently synthetic fibers have serious drawbacks such as high cost, high density, poor recycling and non-biodegradable properties as compared to polymers composites. For these reasons, it needs to the extraction of natural fiber as replacement of synthetic fibers and as for reinforcement polymer composites from plants which is availability from renewable natural resources and the biodegradability of the natural plant fibers present a healthy ecosystem and low costs. The operational parameter (effect of NaOH concentration, soaking time and fiber to polyester ratio) for evaluating of mechanical properties (tensile strength bending strengths and water absorption on to raw and composite fiber were investigated. Preferred result for the desired purpose which have higher mechanical properties has been found as 44.003 MPa tensile strength and 50.81Mpa bending strength at optimum 30:70 fiber to polyester matrix ratio within 6 %NaOH at 48 hour, and the water absorption was lowered at 72 hour with 6% NaOH concentration and 20:80 fiber to polyester ratio which is 3.194%. Treated sisal fibers reinforced polyester composites were better mechanical properties and poor water absorption than untreated fiber.
