Repair Engineering and Design Considerations
This article discusses the three typical repair types for composite structures: temporary repairs, adhesively bonded repairs, and bolted repairs. It contains a table that lists general design requirements and considerations for the repair of composite structures. The article describes ten steps for an engineering repair approach to effectively restore structural integrity to damaged composite components. Management, validation and certification of repairs are also discussed. The article presents design guidelines for analyzing the damage and possible strategies for making a repair. It reviews the three repair schemes used in repair design analysis, namely, core replacement, adhesively bonded patch, and mechanically fastened patch. The article discusses the various pitfalls and problems in repair design for composite structures.
