Abstract :The stress analysis of multi-layered hybrid composite pipes with symmetrical orientation angles, under internal pressure, was investigated. The codes of numerical models were created in ANSYS software for numerical analyses. Two inner surfaces of first model are E-glass fiber/epoxy and two outer surfaces of its are carbon/epoxy (AS4/3501-6). Inner surfaces of second model are carbon/epoxy (AS4/3501-6) and outer surfaces of its are E-glass fiber/epoxy. The problem was studied using a computational tool based on the Finite Element Method (FEM). Each layer of the composite pipes was examined with different orientation angles. T he hoop and shear stresses were obtained numerically for each layer. Also, radial, tangential, axial and shear stresses were determined in the thickness direction of the composite pipes. The shear extension coupling was considered because the lay-up angles with [+ θ, – θ] s layers were in the different radii.Keywords : Hybrid structures, mechanical behavior, composite pipes, finite element analysis (FEA)
