Describe the construction of a bonded honeycomb structure.

• A. A solid aluminum panel with a foam core.
• B. A laminated structure with solid facings bonded to either side of a core consisting of open, six-sided cells.
• C. A woven fabric with no core.
• D. A single sheet of glass with adhesive.

Answer: (B)

A bonded honeycomb structure is a sandwich panel where two solid facings are bonded to opposite sides of a lightweight core made of open hexagonal cells. The hexagonal core provides stiffness and load distribution while keeping weight down, because most of the bending load is carried by the facing sheets and the core simply spaces them apart and resists shear. The core materials are commonly aluminum or specialized composites, and the whole assembly is bonded with an adhesive to create a rigid, lightweight panel. This description matches a laminated structure with solid facings bonded to a core consisting of open, six-sided cells, which is the defining feature of honeycomb construction. Other options describe solid panels with foam, fabric laminates without a core, or a single sheet with no core, none of which capture the distinctive hexagonal-cell core of honeycomb.
