Trends and Challenges on the Development of Hybridized Natural Fiber Composites

ABSTRACT

Fiber reinforced composites are majorly used as structural components in industries and also as a replacement for wood. Fiber reinforced composites are manufactured by reinforcing fibers in the polymeric matrix in appropriate shapes. At the inception, man-made fibers like carbon, glass, and kevlar are used as reinforcements and are proven to be the best in respect to the properties, reinforcing ability and usability. On the other hand, natural fibers like jute, sisal, flax, hemp, vetiver, etc., are nowadays widely used as reinforcements and they are on par with the behavior of artificial fibers. Research studies also confirm that when both man-made and natural reinforcements are used in hybrid form, the composite properties are improved to a greater extent. Under this combination, the composite material gains all the superior properties of individual fibers and when the composite is subjected to different loading, each fiber offers its own maximum resistance. Hence, the composite would be superior in all the properties. The present article gives a detailed insight on the various issues related to synthesis, mechanical characterization and machining of natural fiber reinforced hybrid composites.

摘要

纤维增强复合材料在工业中主要用作结构部件，也可替代木材.纤维增强复合材料是通过适当形状的增强聚合物基体中的纤维来制造的.一开始，碳纤维、玻璃纤维和芳纶等人造纤维被用作增强材料，在性能、增强能力和可用性方面被证明是最好的.另一方面，黄麻、剑麻、亚麻、大麻、香根草等天然纤维目前被广泛用作增强材料，其性能与人造纤维相当.研究还表明，无论是人工加筋还是天然加筋，复合材料的性能都有较大的提高.在这种组合下，复合材料获得了各种纤维的所有优越性能，当复合材料受到不同的载荷时，每种纤维都提供了自己的最大阻力.因此，复合材料在所有性能上都具有优越性.本文对天然纤维增强混杂复合材料的合成、力学性能和加工等方面的各种问题进行了详细的分析.
