The research reported here sought to obtain the optimal winding angle (ϕ) in laminated carbon fiber reinforced polymer (CFRP) composite pipes under patch loading. To observe the sole effect of winding angle on the pipe's mechanical strength, the stacking sequence of the composite laminates ([ϕ/-ϕ/ϕ/-ϕ/ϕ]) was kept constant. An analytical investigation based on linear membrane shell theory was adapted to obtain the radial displacements (w) along the radial direction (z). A double Fourier series expansion was used during the analytical investigation. Two crucial factors were considered when selecting the optimal winding angle: (1) the minimum difference between the inward (compression) and out..
