Composite patch adhesively bonded repair is an advanced repairing method for damaged metallic structure, and in patch designing, it is important to choose appropriate geometrical parameters, which decides mechanical properties of repaired structure. Based on 3D FEM, the model of aluminum plate with a central through crack adhesively bonded repaired with carbon/epoxy composite patch was established, which can take into account residual thermal stress and bending deformation caused by differences of thermal expansion coefficient. SIF was calculated using virtual crack closure technology and compared to evaluate effects of patch geometrical parameters on mechanical properties of repaired structure. The results show that there is optimal patch length and thickness which can make best repairing effect and an effective patch width can reduce SIF significantly, beyond which it is helpless.

Repairing Effect

Composite patch adhesively bonded repair is an advanced repairing method for damaged metallic structure, and patch designing is important before repairing, which decides final repairing effect. Based on 3D FEM, the model of aluminum plate with a central through crack adhesively bonded repaired with composite patch was established, which can take into account residual thermal stress and bending deformation caused by differences of thermal expansion coefficient. SIF was calculated using virtual crack closure technology and compared to evaluate patch designing. The results show that for through centrally cracked aluminum plate, rectangle boron/epoxy patch is the best, and more plies whose fiber direction is parallel to loading direction are, better repairing can be got.
