The 5 layers bidirectional have a higher tensile strength compared to 5 layers multidirectional. While 7 layers bidirectional have a higher tensile strength compared to 7 layers multidirectional. The modulus of elasticity of bidirectional alignment was higher than multidirectional alignment. Bidirectional alignment was better because the external tensile load was equally distributed on all the fibers and transmitted along the axis of the fibers. Whereas in case of multidirectional alignment, fiber axes was non-parallel to load axis, resulting in off axis pulling of fibers and increased stress concentration causing the earlier failure of laminates. Water absorption test showed that multidirectional alignment absorbs more quantity of water compared to bidirectional alignment.
