The transverse shear stiffness of carbon fiber reinforced plastics (CFRP) circular cell honeycomb (CCH) was studied using analytical method, numerical method and experiments, and the equivalent transverse shear modulus of CFRP CCH was found. The in-plane shear modulus of the laminate used for CCH was found by calculating the stiffness of laminate, and the analytical solution of shear modulus of CCH was obtained using a rectangular representative volume element (RVE). Configuration of composite tubes was designed according to the finite element (FE) analyses of CCH. The numerical solution of shear modulus of CCH was found by FE analysis using twin-shear FE model of CCH. The analytical and numerical solutions were corrected using experimental results. The correction coefficient was found, and it is a very important parameter for the study of mechanical property and application of CCH.
