Study on axial compressive bearing capacity of composite stringers in large civil aircraft fuselage
Composite stringer is the main bearing structure of civil aircraft fuselage. The finite element models of hat-shape composite stringer and T-shape composite stringer under axial compressive loads were established by using ABAQUS software. Hashin criterion was introduced to describe the failure of the composites, and the buckling load and the crippling load of the composite stringers were calculated. The corresponding axial compressive tests of the composite stringers were carried out by electronic hydraulic testing machine. The test results were in good agreement with the finite element analysis results, which verified the rationality and accuracy of the calculation model. The numerical calculation method and results in this paper can provide guidance for the structural design of composite stringer in large civil aircraft.
