Adhesive Bonding – Benefits:

  • Well-distributed load transfer when compared to point fasteners
  • Durability – fatigue resistance
  • ‘Sealed’ joints
  • Secondary benefits such as acoustic damping


Joint Design – Key issues:

  • Load transfer – in both typical and ‘abuse’ load cases
  • Thermal expansion – particularly when mating dissimilar composite and metallic substrates
  • Disassembly requirements – for crash repair and end-of-life
  • Design for Manufacture – avoiding wipe-off, ensuring consistent gaps, etc.


Bonding Solution – Selection:

  • Manufacturing ready – appropriate takt-time for handling strength
  • Structural strength within operating conditions
  • Environmental resistance – matches or exceeds the substrates
  • Hybrid fastener/bonding solutions – can accelerate assembly and affect joint performance


Key Manufacturing Technologies for Production:

  • Automated surface preparation – cleanliness and activated bond surfaces
  • Repeatable adhesive deposition
  • Robust jigging for geometry control, joint creation and accelerated curing
  • Non-destructive evaluation of bonds
