Název v původním jazyce

Modal analysis of a laminate panel with 30 mm notch focused on the effect of a functionally oriented fabric layup with 20 mm wide carbon strips

Popis výsledku v původním jazyce

Functionally oriented fabric (FOF) is a technical woven textile with irregularly distributed secondary material strips in both warp and weft directions. Strips form a pattern and locally improve the mechanical properties of a laminate, especially around an opening or within a large shell structure. The subject of this work is to analyze the effect of three FOF laminate layups on natural frequencies of the laminate panel with a notch. The layups are “0/90”, “0/30/60” and “0/45” as the most used configurations for quasi-isotropic laminate structure. The width of strip is 20 mm, span of strips is 30 mm and there is a 30 mm circular notch in the center of the plate. Numerical modal analysis has been made on laminates with 6 laminae through thickness so the influence of geometry variation can be neglected. This study highlights the potential of FOF to improve the dynamic performance and lifespan of laminated composite structures used in various engineering applications.
