Mechanical Behavior of Raavi and Pineapple Fiber-reinforced Hybrid Polyester Composites

Abstract

The raising requirement of plastic materials and their production in advanced engineering were having significant impact on environment. This investigation aims to observe the potential of agro waste residues, such as Raavi and Pineapple fiber, as reinforcement in Polyester GP51 matrix as an alternative to plastic-based components for structural applications. The composites were developed by using compression molding technique by varying the fiber content in percentage. Single fiber test and Fourier transform infrared spectroscopy were used to find the ability of the fiber. The composites were fabricated and tested as per ASTM standards. The tensile strength, flexural test, and impact strength were studied and morphological study was carried out by using scanning electron microscopy and energy dispersive X-ray analysis. The result shows that the Raavi and Pineapple fiber polymer composites have achieved considerable increasing value of mechanical properties of the composites. This investigation suggested the possible way of utilizing hybrid fiber from the agro-based waste in polymer matrix composites.
