Abstract:

For penetrability damaged composite components, composite material rounded patch bolted repairing was used to recover strength. This paper introduced the method to analyze the effect of composite patch bolted repairing parameters. The authors utilized the Double Plate-DOF Spring element in the finite element model to analyze the repair efficiency of the bolted repairing method with MSC/NASTRAN and obtained some valuable conclusions.

Key words: composite, bolted repair ing, finite element
