Physio-Mechanical Characterization of Jute/Kevlar Hybrid Composites Coupled with MADM Approach for Selection of Composites

ABSTRACT

The present study aims at exploring the possible usage of natural and synthetic fiber-reinforced hybrid composites for structural applications. Jute and Kevlar-reinforced hybrid composites with different stacking sequences, namely, jute-kevlar-jute (JKJ) and kevlar-jute-kevlar (KJK) were fabricated using the vacuum bagging method and compared with the jute-jute-jute (JJJ) and kevlar-kevlar-kevlar (KKK) composites. The physical and mechanical properties of the proposed composites namely; density, void content, water absorption, tensile strength, flexural strength, and impact strength were determined experimentally. The physical characterization revealed that there is no appreciable variation in the density of all the four proposed composites. Hybridization results in better resistance to water absorption compared to complete natural fiber-reinforced composite. Mechanical characterization reveals that JKJ composite can be a potential replacement for KKK composite in structural applications requiring good tensile and flexural strength. However, impact study reveals that KKK composites exhibit better impact strength compared to their counterparts. However, hybridization of composites results in enhanced impact strength compared to complete natural fiber-reinforced composite. Finally, a multi-attribute decision-making (MADM) approach is adopted to select the best among the proposed composites considering all the physical and mechanical properties.

摘要

本研究旨在探索天然和合成纤维增强混杂复合材料在结构应用中的可能用途. 采用真空装袋法制备了黄麻和芳纶纤维增强混杂复合材料, 并与黄麻和芳纶纤维增强混杂复合材料进行了比较. 拟用复合材料的物理和机械性能, 即; 实验测定了密度、空隙率、吸水率、拉伸强度、弯曲强度和冲击强度. 物理表征表明, 所有四种拟用复合材料的密度没有明显变化. 与完整的天然纤维增强复合材料相比, 杂交具有更好的吸水性. 力学特性表明, JKJ复合材料在需要良好拉伸和弯曲强度的结构应用中可以作为KKK复合材料的潜在替代品. 然而, 冲击研究表明, 与同类材料相比, KKK复合材料具有更好的冲击强度. 然而, 与完整的天然纤维增强复合材料相比, 复合材料的杂交提高了冲击强度. 最后, 采用多属性决策 (MADM) 方法, 在考虑所有物理和机械性能的情况下, 从所提出的复合材料中选择最佳材料.
