The purpose of this study was to determine the optimal combination of shell, fibre and liner of a composite pressure vessel resistant to bursting strength. The optimal range of fibre and shell thicknesses was predetermined to achieve an improved sustainable composite pressure vessel. Through the design of the experiment adopted in the Minitab software, the Box-Behnken was used in the optimization of fibre and shell held as dependent variables while the liner was held as the independent variable. Therefore, using the Minitab software version 2016 allowed the combination of these variables to yield an optimal composite on two profiles considered in this study. The generated results of the combination of the ultimate factors value yield on two profiles an optimal design with a probability of 95% for it to be normal. These factors the liner, fibre and shell, have been found to have different influences on the hoop stress response and to each other. With the objective of the study achieved, optimization of the first profile was found with a liner of 4.8 mm, a fibre of 0.5 mm and shell thickness of 2.7 mm. For the second profile, optimization was recorded at a liner of 9.5 mm, 2.1 mm of fibre and 5.5 mm of shell thickness. In brief, the determination of these optimal parameters was obtained with a strength improvement of 4% and 33% weight reduction comparatively to the whole metallic pressure vessel. In addition, hoop stress values of 123.43 MPa and 123.84 MPa, Von Mises values of 178.56 MPa and 178.7 MPa and Tresca values of 179.48 MPa and 179.62 MPa were obtained on Profile 1 and 2, respectively. These values led to the consideration of profile 1 as the most optimal of the two profiles studied.
