In a bonded honeycomb structure, what are the outer layers bonded to the core called?

• A. Facings
• B. Spacers
• C. Caps
• D. Sheets

Answer: (A)

In a bonded honeycomb structure, the outer layers bonded to the core are called facings. These thin outer sheets form the exterior surfaces of the sandwich panel and carry the primary loads, while the core provides separation and shear resistance to keep the panel lightweight yet stiff. Facings are also known as face sheets or skins. Terms like spacers refer to internal elements that separate parts of the core and are not the outer bonded layers, and caps or sheets are either not standard terminology or too generic to describe the bonded outer layers.
