A FRP curve sandwich panels with varied thickness is studied.The stress distribution of the FPR curve sandwich panel is analyzed in tension,shear and flexure,which shows the maximum of stress happens in the support and decreases with panel length.Based on the failure standard of Tsai-Wu and the first、third principal stress,the material properties such as the thickness of facing sheet,the thickness of core,and the paving angle of facing sheet are considered in the load combination.The result indicates the strength performance is improved by the increment of the thickness of facing sheet,and the thickness of core;and paving angle of 0/90/0/90.
