Parameters Selection for Enhanced Mechanical and Wear Properties of Natural Fiber Reinforced Hybrid Composites Using PSI Technique

ABSTRACT

Natural fibers are being used more often for composite preparation these days. Natural fiber-reinforced polymer composites have been used in a wide range of engineering domains due to their significant benefits over synthetic fiber composites. The interfacial interaction with the matrix content and water absorption are two main disadvantages of using natural fibers. The effects of natural fibers (Abutilon indicum, luffa cylindrica, and Prosopis juliflora), chemical treatments (NaOH, KOH, and silane), and fillers (CaCO₃, Al₂O₃, and TiO₂) on mechanical and wear properties were investigated in this study. The silane-treated fiber-reinforced composite outperformed the other two treatments and untreated fiber-reinforced composites in terms of mechanical properties. In the present study, multicriteria decision-making (MCDM) approaches were used to cope with the difficulty of choosing good estimate over a wide variety of opportunities. The predicted optimal combinations for good mechanical and wear outputs of the composite were chosen using a performance selection index (PSI) process. Characterizations such as FTIR and SEM are conducted to verify the applicability of hybrid composites in temperature, chemical, and humid environments. The bonding between the treated fibers and matrix strengthened with fiber treatment and filler addition, according to the SEM study.

摘要

如今,天然纤维越来越多地用于复合材料的制备. 与合成纤维复合材料相比,天然纤维增强聚合物复合材料具有显著的优势,因此在工程领域得到了广泛的应用. 界面与基体含量的相互作用和吸水性是使用天然纤维的两个主要缺点. 本研究考察了天然纤维(印度阿布替隆、丝瓜和朱丽叶前草)、化学处理(NaOH、KOH和硅烷)和填料(CaCO3、Al2O3和TiO2)对机械和磨损性能的影响. 硅烷处理的纤维增强复合材料在力学性能方面优于其他两种处理和未处理的纤维增强复合材料. 在本研究中,多准则决策(MCDM)方法被用于解决在各种机会中选择良好估计的困难. 使用性能选择指数(PSI)过程选择复合材料良好机械和磨损输出的预测最佳组合. 通过FTIR和SEM等表征,验证了杂化复合材料在温度、化学和潮湿环境中的适用性. 根据SEM研究,处理后的纤维与基体之间的结合通过纤维处理和填料添加得到加强.
