The ultimate bearing capacity of quartz fiber and carbon fiber hybrid stiffened panels under shear load is studied and its damage mode is analyzed. The two-dimensional Hashin criterion and the secondary nominal stress criterion are used as the in-plane and interlaminar failure criteria of hybrid composite stiffened panels. Thus，a shear failure analysis model considering progressive damage is established， and the hybrid stiffened panels is modeled and solved on the ABAQUS finite element software platform. The shear tests of quartz fiber and carbon fiber hybrid stiffened panels are carried out to measure their failure loads and obtain their typical failure modes. The relative error of buckling load and failure load between simulation results and test results is within 15%， and the failure mode is consistent， which verifies the feasibility and effectiveness of the modeling and analysis method.
