Weibull probability model for tensile properties of kenaf technical fibers

Tensile properties of kenaf technical fibers were investigated and has been statistically analysed by Weibull weakest-link model. The tensile strength of kenaf fiber has been verified to follow this two-parameter Weibull distribution. The Weibull modulus varied between 1.7 and 2 for fiber tensile st...

Description
Summary:Tensile properties of kenaf technical fibers were investigated and has been statistically analysed by Weibull weakest-link model. The tensile strength of kenaf fiber has been verified to follow this two-parameter Weibull distribution. The Weibull modulus varied between 1.7 and 2 for fiber tensile strength, and 1.6 to 2.4 for fiber Young’s modulus, meanwhile the scale parameter varied between 204.7 MPa and 282.2 MPa for fiber tensile strength and for Young’s modulus between 14.8 GPa and 21.2 GPa. Lowest modulus was estimated with the high number of defects contained along the fibers. The present study presented that the Weibull distribution describes the experimentally measured strength data more appropriately.
