The present research problem deals with the micromechanical analysis of a unidirectional continuous hybrid fiber - reinforced composite lamina. Three - dimensional models along with governing boundary conditions have been developed fr om the Representative Volume Elements (RVE) which are idealized as an array of square unit cells. The stress - strain relation in the finite element models takes place according to three - dimensional elasticity theory. The hybrid lamina consists of two differ ent fibers of T300 and SGLASS materials, and epoxy matrix. The micromechanical analysis includes the evaluation of mechanical properties of the hybrid lamina at the fiber - matrix interface for perfectly bonded interfaces. In this phase of the work, the long itudinal Young’s modulus (E1), Poisson’s ratios (ν12 and ν13) are determined for a hybrid lamina for different volume fractions of fibers. In this case, the lamina is subjected to uniform pressure load in the In Plane Transverse direction of the composite lamina and no debond is considered at the fiber - matrix interfaces
