Bonded joints in composite structure are attractive because they

  • A.Are easier to inspect than bolted joints
  • B.Can be disassembled readily
  • C.Require no surface preparation
  • D.They avoid cutting the load-carrying fibres

Answer: D

Drilling cuts the very fibres that carry the load, so a bonded joint that transfers load through shear over an area is inherently more efficient. The difficulty is that a weak bond is hard to detect, which is why critical bonded joints often carry fasteners as well.
