Abstract

The present investigation studies the micromechanical behaviour of the square unit cell of a Fiber Reinforced Composite lamina. A three-dimensional finite element model has been developed from the unit cells of square array of the composite to predict the Young’s modulus (E2) and poison’s ratios (ν23, ν21) of Graphite and Boron fiber reinforced lamina. The stresses at the fiber-matrix interface are also determined from this model.  The finite element software ANSYS has been successfully executed to evaluate the properties and stresses.  The variation of the stresses at the fiber-matrix interface with respect to the angular location is discussed.
