What type of defect in a bonded honeycomb structure can be repaired using the potted repair method?

• A. Filling a hole
• B. Cracks along the edge
• C. Delamination
• D. Surface crazing

Answer: (A)

Potted repair is used to restore a damaged void in the honeycomb core by filling it with a resin-filled material that cures into a solid mass. This reestablishes the core’s stiffness and provides a solid foundation for re-bonding the face sheets. It's specifically suited for holes or voids in the core, where material is missing and a solid fill can be injected to recreate the load path through the structure. Cracks along the edge, delamination, and surface crazing involve the skin-to-core bond or the surface finish and require different repair methods such as edge repair, patching, or cosmetic fill, not a core fill. Therefore, filling a hole is the defect best repaired with the potted method.
