Elimination of huge waste produced by mankind has become a sensitive issue in the present scenario. To preserve our earth and to make it pollution free, it becomes necessary to reduce the garbage causing pollution. Plant fibers are the best and abundant sources of natural reinforcement readily available. These fibers can be used for fabrication of composites which can reduce the problem of pollution (garbage). In this study composites of jute are fabricated by hand layup and compression molding using reinforcement material of jute and matrix material as epoxy resin of different areal densities (4, 5, 5.5 and 7.5 kg/m²) or layers and produced jute epoxy composites are tested for physical, mechanical and water absorption behaviour to meet the demands of the fiber based jute composites. It was observed that the different mechanical properties of the fiber based jute epoxy composites were significantly influenced by the areal density and number of layers It was obtained that there was an increase in mechanical properties like tensile and flexural strength of jute-epoxy composite with areal density up to 5.5 kg/m² and further these properties decreases with increase in areal density. On the other hand, the impact strength and water absorptivity increases with increase in areal density and number of layers of composite.

黄麻复合材料的力学性能和吸水性能研究

在目前情况下，消除人类产生的巨大浪费已成为一个敏感问题。为了保护我们的地球并使其免受污染，有必要减少造成污染的垃圾。植物纤维是现成的天然增强的最佳和丰富来源。这些纤维可用于制造复合材料，从而减少污染（垃圾）的问题。在这项研究中，黄麻的复合材料是通过手工铺层和压制成型，使用黄麻的增强材料和基体材料作为不同面密度（4、5、5.5和7.5 kg / m ^2的环氧树脂）制成的。）或层和生产的黄麻环氧复合材料的物理，机械和吸水性能经过测试，以满足纤维基黄麻复合材料的要求。观察到，纤维基黄麻环氧复合材料的不同机械性能受到面密度和层数的显着影响。发现随着面密度的增加，黄麻环氧复合材料的机械性能（如拉伸强度和弯曲强度）有所提高最高可达5.5 kg / m ^2，并且这些特性随面密度的增加而降低。另一方面，冲击强度和吸水率随面密度和复合材料层数的增加而增加。
