چکیده
The composite pressure vessels are used in varieties of applications such as automobile, aeronautics and chemical engineering. Besides these, they have become very popular in oil and gas transport industries. These pressure vessels are experience very high internal pressures during their operation. The present paper demonstrates a study on cylindrical section of carbon fiber reinforced polymer (CFRP) composite pressure vessel having four layers. The pressure vessel is designed and modeled using the finite element software ANSYS 11. The step by step procedure for the finite element modeling of multilayered composite pressure vessels has been discussed in the paper. The modeling is performed for both hoop and helical windings of the fibers in pressure vessel. For helical windings the layers were oriented symmetrically for [+25°/-25°]s, [+35°/-35°]s, [+45°/-45°]s, [+55°/-55°]s, [+65°/-65°]s, and [+75°/-75°]s, orientations. The burst pressure for each of the fiber orientations is predicted based on the Tsai-Wu failure criteria.
