Abstract

Prediction of shear moduli of Graphite-Boron-hybrid fiber and epoxy matrix composite lamina with fiber-matrix interface debond is carried out in the present analysis. Square unit cell is adopted for developing three-dimensional finite element models. The finite element models are validated by comparing the numerical results with the existing literature and found close agreement. Later these finite element models are extended to predict the shear moduli of Graphite-Boron fiber-epoxy matrix hybrid composite with partial debond at the fiber-matrix interfaces for 60% fiber volume fraction (Vf). The finite element software ANSYS 11.0 has been successfully executed to evaluate the properties. The effect of debond on these properties is discussed.
