Abstract

Fiber reinforced composite is a composite material consisting of a matrix reinforced by a fabric. Shear strength can be defined as the maximum shear stress that a material is capable of sustaining. Shear strength is calculated from the shear fracture load and the shear loaded area. Interlaminar shear stress (ILSS) is the shear stress observed between the laminae of a laminate. The objective of the present work is to perform finite element analysis on neat and CNT reinforced S glass epoxy composite (CRSE) using ANSYS software to estimate the instantaneous shear modulus (ISM) and observe the effect of notch separation on the measured ILSS. In S glass epoxy composite (SGEC), least and peak values of ILSS and ISM are 14.79 MPa, 35.35 MPa and 15.19 MPa, 33.12 MPa respectively when the notch separation is 5 mm and 1 mm.
