Figure 8: Classical critical loads and reduced stiffness critical loads versus the varying thickness of a single 9 0 ply in the case of [ ( 9 0 ) 𝑡 9 0 , ( 0 ) 𝑡 0 , ( 0 ) 𝑡 0 ] 𝑠 with the total shell thickness unchanged, the total fibre volume fraction fixed at 0.5, and the fibre volume fraction of the 9 0 ply fixed at 0.75.
