The main concern of this work is to investigate the influence of number and orientation of ply on tensile properties of hybrid composites. Hybrid composites are those materials which consist of two or more distinct fibers embedded in the same matrix. For this analysis, the elastic behavior of individual fiber-reinforced composite lamina is required. The properties of a single lamina of composites can be determined by the micromechanical homogenization. From this analysis, it is seen that elastic modulus, Poisson's ratio, and shear modulus are the functions of the volume fraction of the fiber and matrix. These properties can be further used for analysis of hybrid composite laminate. In this work different hybrid composites material with a different number of plies and orientations are used to simulate with finite element software. At first, a 3D model of three-ply is used for the simulation. The other model with four, five and six-ply has been used. The influence of number and orientation of ply on tensile properties of hybrid composites is the main goal of the work. The comparison of stiffness between different ply models has established that the number ply influences the strength of hybrid composites. From this work, it is seen that as number ply increases the tensile strength also increases. For the investigation of the influence of the ply orientation, different orientations of ply are used. From different simulation results, it is seen that ply orientation with 00 is the best for the tensile strength.
