A comparative study on tensile strength of silk and sisal fibre by regression modelling

Abstract

The instantly growing performance of natural fibre composites is replacing the traditional materials to enhance the efficiency and get a consistent system. This is possible by producing composites with enhanced material properties, like being lighter and more resistant in nature. On the basis of high strength, rigidity and along with low density properties, polymeric composites with natural reinforcing fibre have more demand. Natural fibres are collected from many sources but two of them are the most prominent sources, they are plant fibres and animal fibres. The characteristics study of single fibre is having more importance before the composite fabrication and that ultimately provides a proper fibre selection and hybridization in different field of application. In this paper the principal objective is to test the tensile behaviour of Bombyx mori silk and sisal fibre at different strain rate along with three different gauge lengths. The regression analysis has been done using MINITAB software and for each fibre a linear regression equation was established. From the regression analysis the R 2 value was found out and ultimately silk fibre results better tensile strength as compared to sisal fibre. That also indicates excellent mechanical performance can be achieved by hybridization with silk fibre.
