Abstract

— In this study, the torsional stresses of hollow circular shafts manufactured from composite materials and with different orientation angles were researched. For hollow circular composite shafts; carbon fiber were used as the fiber materials, while epoxy resin was used as the matrix material. 80mm, 200mm and 250mm long composite shafts of different inner diameters were used. The hollow circular composite shafts were manufactured at θ=45°, 60°, 75°, 80°, 88° orientation angles. Filament winding method was preferred when manufacturing the composite shafts. The mechanical torsion tests of hollow circular composite shafts were separately repeated for each sample. The obtained results were evaluated among themselves in terms of the length of the shafts, the diameter of the shafts and the orientation angle, after which they were transferred to the graphics. The obtained results of experimental and numerical analyses were presented in graphs and the necessary considerations were made. The experimental and numerical analysis results were found to be close to each other
