Effect of Fiber Orientation on Mechanical Properties of Sisal Fiber Reinforced Epoxy Composites

ABSTRACT This present work evaluated the effect of fiber orientation on mechanical properties of sisal fiber reinforced epoxy composites. In this work sisal fiber is used as reinforcement which treated with NaOH solution for enhancing the bonding strength between fiber and resin by removing moisture contents. Samples of different orientations of sisal fiber reinforced composites were fabricated by compression molding and investigated their mechanical properties like tensile strength and flexural strength. The work of this experimental study has been carried out to determine the mechanical properties due to the effect of sisal fiber orientations such as 0°/90°, 90° and ±45° orientation. The results of this study indicate the orientation 90° shows the better mechanical properties compare than 0°/90° and ±45°.
