Abstract
The pressure vessels are used to contain fluids that are at a pressure that is significantly different from the atmosphere. İn the present study, multiple carbon fibre reinforced composite pressure vessels were modelled in ANSYS with the variation of the fibre orientation angle. Internal pressure was applied to the pressure vessels, then it was considered to be failed if the first ply burst failure was occurred. The Tsai-Hill failure criterion was applied to the model. The fibre orientation angle of 55°/-55° was found to have good strength. The deformation modes changed from the lateral deformation at lower fibre orientation angles to the axial deformation at higher angles. For axial loading the lower fibre orientation angle has better strength. The fibre orientation angle of 30° showed better properties for the axial loads. For the combination of the axial and the internal pressure as the load, the 55° orientation angle showed better resistance.
