Table 3 Mechanical property of the carbon fiber/epoxy composite material. Variable ρ is mass density, Ei, νi j, Gi j, Si,T/C,and Si j are Young’s moduli, Poisson’s ratios, shear moduli, normal strengths, and shear strengths in corresponding directions. Ui,T/C are tensile/compressive fracture energy in the corresponding directions32.
