A process of analyzing the performance evaluation of sisal fiber in fiber reinforced composites

Abstract

Ecological pollution is the most essential thing in the fast-growing world. Many scientists were concentrated to develop environmental pollution-free composite materials and products according to environmentally sustainable principles. So those synthetic fibers were replaced by natural fibers due to less expensive, easy availability, minimal waste removal difficulties, comparable strength, non-toxicity, and ecologically friendly environment. Sisal fiber is one of the most significant natural fiber which is obtained from a Sisal tree and available more number in the state of Andhra Pradesh. In the current research, the reinforcement of Sisal fiber with epoxide composites has been formulated and the mechanical characteristics of those composites are reviewed. In this research, the stir casting method was utilized to prepare the composite specimens with the various fiber weight fractions of 0–30% and the pressure was applied at ambient temperature. As per the ASTM standard, the prepared composites were crushed into small pieces for various experiments. The specimens have been exposed to hardness, density, and mechanical testing like impact, flexural and tensile loading. The highest possible hardness, flexural strength, density, and tensile strength are attained for the material fabricated with the 20 wt% reinforced Sisal epoxide composites. The fiber matrix was evaluated, and the structure of the fractured surfaces was examined through performing SEM, i.e. scanning electron microscope analysis.
