| Abstract: | Composite is widely used in the structure of the aircraft, study of composite stiffened panel repair has become an important problem to be settled in the repair for the composite laminated structures. Finite element analysis models are performed in order to calculate the buckling factor of the composite laminates with a stepped-lap. The effect of repair parameters on the stability of repaired structures are discussed in detail, such as the radius of patch, the number of patch step, the width of composite stiffened panel structures. |
