    A study was conducted to establish allowable limits for carbon fiber reinforced plastic (CFRP) spacers and improve analysis reliability by incorporating variable factors. First, stress-strain relationships were established for unidirectional lamina and for lamina in arbitrary directions. Classical laminated theory (CLT), a general CFRP analysis model, assumes thin laminated plates with constant in-plane strain across thickness, suitable for unidirectional laminates but inadequate for different direction laminates due to neglect of lateral shear deformation. Therefore, to account for lateral shear deformation effects, the first-order shear deformation theory (FSDT) was applied, addressing bending or twisting of laminates due to normal stress in the x-direction. Design limits were then set for torsional shear strength, buckling strength, and critical speed to establish standards for CFRP spacer products. Analytical verification of these design limits was performed to ensure compliance with established standards.
