Finite Element Analysis of Flexural Behavior in Full-scale Tapered FRP Pole Structures: Influence of Fiber Orientations, Circumferential Layers, and Carbon Fiber Substitution. In this study, we present a finite element modeling analysis of the nonlinear behavior of laterally loaded full-scale tapered fiber-reinforced polymer (FRP) pole structures. The study explores the impact of various parameters, including fiber orientations in longitudinal and circumferential layers, the number of circumferential layers, and the substitution of glass fiber with carbon fiber in the FRP pole compositions.
The FRP poles in question were manufactured using the filament winding technique, with E-glass fiber and epoxy resin as the primary materials. Our analysis results exhibit a significant correlation between the finite element analysis and experimental data, emphasizing the critical role of fiber orientation in determining flexural behavior.
The findings underscore the advantages of incorporating circumferential layers and highlight that enhanced strength can be achieved by incorporating both outer and inner circumferential layers alongside longitudinal layers. Moreover, substituting carbon fiber for glass fiber in the FRP poles results in notable improvements, with increased total load capacity and stiffness as the percentage of carbon fibers rises.
