The Flexural strength and the Tensile strength were seen to increase considerably with fibre volume fractions for parallel fibre reinforcement. The experimentally observed tensile properties (tensile strength and modulus) of short sisal fibre-reinforced LDPE with different fibre loading have been compared with the existing theories of reinforcement. EFFECT OF FIBRE LENGTH AND PERCENTAGE OF SISAL ON STRENGTH OF CONCRETE. The tensile strength of the fibres decreased after hydrolysis and NaOH treated fibres had the lowest tensile strength followed by enzyme treated fibre. The tensile strength, modulus and toughness values of sisal fibre decreased with increase in temperature. The tensile and flexural properties of sisal fibre epoxy composite both in unidirectional and in the mat form are found to be maximum at 30 wt %. This paper presents the results of the experiments undertaken to evaluate various physical and mechanical properties of hemp fibres. The regression analysis has been done using MINITAB software and for each fibre a linear regression equation was established. Jitendra Dalvi. It was found that the tensile strength of sisal fibre composites improved when 0 ° oriented fibres were positioned at the extreme layers of the composites compared to 90 ° oriented fibres. Cement, a constituent of concrete releases huge amount of greenhouse gases by manufacturing. However, the issues of relatively high moisture content of fibres, … This work investigates the tensile and flexural properties of sisal fibre reinforced epoxy composite. 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. considered as an alternate fibre to improve the tensile strength properties of conventional concrete. Sisal fibres extracted from the leaves of Agava sisalana plants 3, 5, 7 and 9 years old were tested at different temperatures for tensile strength, elongation, toughness and modulus. It was found that the tensile strength of sisal fibre composites improved when 0 º oriented fibres were positioned at the extreme layers of the composites compared to 90 º oriented fibres. The properties of hemp fibres were found to be good enough to be used as reinforcement in composite materials. The tensile stress at maximum load also decreased from 237 MPa to 192 MPa for enzyme treated fibres. The mean tensile strength and modulus values of 4 µm diameter hemp fibres were 4200 MPa and 180 GPa; whereas for hemp fibre of 66 µm diameter, the corresponding values were 250 MPa and 11 GPa, respectively (Prasad and Sain 2003). 4. No increase in Flexural and Tensile strengths was observed for the chopped fibres reinforcement. Sisal fibers (Agave‐Veracruz) have been used as reinforcements in low‐density polyethylene (LDPE). The tensile strength of SMA mixes with fibre additive shows increasing trend up to 0.3% and it is found to be decreasing at 0.4% fibre content. https://doi.org/10.1016/j.matpr.2020.10.249.
