    Free Vibration Characteristics of Banana/Sisal Natural Fibers Reinforced Hybrid Polymer Composite Beam
    (Elsevier Ltd, 2016) RAJESH, M.; Jeyaraj, P.; Nagarajan, N.
    Natural fibers having more advantage compared to man-made fiber, such as glass, carbon, Kevlar fiber. But due to the hydrophilic nature of natural fiber gives poor adhesion between fiber-matrix. This will decrease the properties of polymer composite. In this study influence of surface pre-treatment with sodium hydroxide and hybridization effect of natural fiber are investigated on flexural test and free vibration behavior. In this work sisal and banana natural fibers are used in short and random orientations to prepare the polymer composites using compression moulding method. From the experimentation, it is found that chemical treatment improves the mechanical and free vibration properties of polymer composites due to the enhancement of interfacial bond between fiber and matrix as the result of chemical treatment. © 2016 The Authors.

    Study on Physical and Mechanical Behavior of Bauhinia Vahlii Fiber Filled Glass–Epoxy Hybrid Composites
    (Springer Science and Business Media Deutschland GmbH, 2023) Ray, R.; Das, S.N.; Mohapatra, A.
    Epoxy is well-suited for a number of industrial applications because of its versatility and its diversity. In many high-performance fields however, the overall use of epoxy limited its employment due to delamination, intrinsic fragility, low impact resistance and hardness to fractures. Epoxy's limitations can be overcome through inclusion and modification prior to industrial use. The present research describes the development of hybrid composites made of epoxy reinforced with glass fiber and filled with Bauhinia Vahlii fiber. Bauhinia Vahlii (BV) found to be most promising natural fiber for manufacturing composites for its superior mechanical as well as thermal properties. In this study, the incorporation of BV fiber on physical and mechanical behavior of glass–epoxy composites was investigated. Various composite compositions with three distinct natural BV fiber percentages (4, 8, 12%) were fabricated using a hand layup technique. The results showed that increasing the percentage of natural fiber concentration improves mechanical qualities, however at larger BV fiber loading, the strength reduces due to presence of more voids which signifies poor bonding. © 2023, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.
