The use of natural fibers as a substitute for synthetic fibers as reinforcement in polymer based composites is finding prominence nowadays. The present article deals with the comparative study of the biodegradable flexible composites fabricated using jute fabric (J) and rubber (R) with different configurations namely Jute/Rubber/Jute (JRJ), Jute/Rubber/Rubber/Jute (JRRJ) and Jute/Rubber/Jute/Rubber/Jute (JRJRJ) using their tribo-mechanical properties as the attributes making use of multi attribute decision making approach (MADM) namely Technique for order of preference by similarity to ideal solution (TOPSIS). Tensile strength, tear strength, interlaminar shear strength and specific wear rate of the proposed composites are chosen as the attributes for comparison using TOPSIS. The results show that JRJRJ is best configuration among the considered configurations of flexible composites providing overall best tribo-mechanical properties and fractography study shows that the proposed flexible composites undergo failure mainly due to matrix tearing in case of tensile and tear test as opposed to matrix cracking in case of stiff composites. Also, wear study reveals that rubber exhibits better resistance to wear. This study exhibits the efficient application of statistical based MADM tool TOPSIS for material selection.

绿色柔性复合材料的摩擦力学表征与优化

如今，在基于聚合物的复合材料中使用天然纤维替代合成纤维作为增强材料非常重要。本文涉及使用黄麻/橡胶/黄麻（JRJ），黄麻/橡胶/橡胶/黄麻（JRRJ）和黄麻不同结构的黄麻织物（J）和橡胶（R）制成的可生物降解的柔性复合材料的比较研究。 / Rubber / Jute / Rubber / Jute（JRJRJ）将它们的摩擦机械特性用作属性，并利用多属性决策方法（MADM），即通过与理想解决方案相似的优先顺序技术（TOPSIS）。选择所提出的复合材料的拉伸强度，撕裂强度，层间剪切强度和比磨损率作为使用TOPSIS进行比较的属性。结果表明，JRJRJ在考虑的挠性复合材料构型中是最佳构型，提供了总体上最佳的摩擦机械性能，并且分形研究表明，所提出的挠性复合材料遭受的破坏主要是由于在拉伸和撕裂试验下发生的基体撕裂而不是基体开裂如果是硬质复合材料。另外，磨损研究表明，橡胶表现出更好的耐磨性。这项研究展示了基于统计的MADM工具TOPSIS在材料选择方面的有效应用。磨损研究表明，橡胶具有更好的耐磨性。这项研究展示了基于统计的MADM工具TOPSIS在材料选择方面的有效应用。磨损研究表明，橡胶具有更好的耐磨性。这项研究展示了基于统计的MADM工具TOPSIS在材料选择方面的有效应用。
