Functionally oriented fabric (FOF) is a woven textile with irregularly distributed secondary material strips in both warp and weft directions. Strips locally improve mechanical properties of a laminate, especially around an opening. Major material is a low-cost glass fiber roving and minor material is a high mechanical property roving, such as carbon fiber. The subject of this work is to analyze the effect of different FOF laminate layups on natural frequencies of the laminate with a notch. The layups are [0/90]s, [0/30/60]s and [0/45]s as the most used layups for isotropic homogenization in laminate structures. The width of strip is 30 mm, span of strips is 10 mm and there is a 10 mm hole (a notch) in the center of the panel. Modal analysis has been made on laminates with 6 laminae through the thickness so the influence of geometry variation can be neglected. The benefit of a functionally oriented fabric structure is in increased natural frequency for twisting (1st and 3rd) and bending (2nd and 4th) modes in comparison with pure glass laminate. The increase in frequency in 1st mode is -2 % for [0/902] layup, 20 % for [0/30/60] layup and 30.5 % for [0/452] layup; increase in 2nd mode is 40.5 % for [0/902] layup, 41 % for [0/30/60] layup and 57 % for [0/452] layup; increase in 3rd mode is 9 % for [0/902] layup, 15.5 % for [0/30/60] layup and 30.5 % for [0/452] layup; and increase in 4th mode is 35.5 % for [0/902] layup, 37 % for [0/30/60] layup and 52.5 % for [0/452] layup. These enhancements help to prevent resonance in standard operating frequencies of mechanisms and machines, thus extending their operational lifespan. Additionally, the strategic placement of functional material strips around structural openings provides increased stiffness without the need for extra layers, effectively reducing the laminate's overall mass. This study highlights the potential of FOF to improve the dynamic performance and lifespan of laminated composite structures used in various engineering applications.
