In this work, the stress-strain field is estimated through the application of classical laminate theory. The composite material studied is a hybrid composite made from plant fibers and synthetic fibers. The law of mixtures was used, to identify, the elastic properties of the studied hybrid composite materials. The effect of fiber orientation on the mechanical behavior of the composite material is analyzed. It should be noted that the orientation is a significant parameter affecting the amplification of the stress and strain field in the material and consequently on the safety and integrity of the structure.
