1.1 Main requirements and problems

• Bonding reliability and durability

  In the aeronautics sector, epoxy adhesives have been in industrial use for 50 years, ensuring reliable, durable bonding - performance figures that have been well known for several decades.

  The only remaining problem, as with other types of adhesive and composites themselves, is resistance to water and humidity, which can slowly migrate into the adhesive joint or composite and cause delamination after 10 or 20 years, requiring periodic inspection.

• Fatigue resistance

  Fatigue resistance is excellent for both composites and adhesives. It should be remembered that...
