Özet

In this study, multi-layered composite pipes with varied orientation angles and subjected to internal pressure were investigated by using the 3-D finite element method (FEM) and through experimental tests. The composite pipes were made of E-glass and T300/934 carbon fiber. The studies were carried out experimentally, analytically and numerically. The T300/934 carbon fiber reinforced composite pipes and E-glass reinforced composite pipes were given numerical model codes via ANSYS 14.5 software. These models were then compared with analytical results in the literature and with the experimental results. Finite element analyses (FEA) were carried out to predict failure loads. Each layer of the composite pipes was numerically examined from various orientation angles. Hoop and shear stress wereobtained numerically for each layer. Radial strain and radial stress were achieved in the radial direction of the composite pipes. Shear extension coupling was considered because the layup angles with + theta and - theta layers were in varied radii. Subsequently, the effects of the orientation angles were examined for all models. Moreover, it was found that an embedded adhesive joint is important for industrial applications.
