Composite Repair

As OEMs design and build more lightweight aircrafts with composite parts and structures, the need for more user-friendly and proven bonded repair solutions becomes critical for airline operators and MRO shops. Aircraft materials used in the construction and repairs of complex composite structures can be challenging for the aerospace industry, with the various types of damage requiring different repair approaches and demanding innovative solutions.

Under the LOCTITE® brand, Henkel offers ready-to-use adhesive solutions for a variety of composite repair requirements:

  • Bonding, potting, and filling
  • Laminating and wet lay-up
  • Out-of-autoclave processing
  • Specialty repair – high temperature, surfacing film, and lightning strike

When it comes to aircraft components, structural integrity is essential. This is why Henkel offers aerospace manufacturers composite bonding, potting, and filling products that bond or join composite sub-components with excellent chemical and environmental resistance, variable viscosity, and extraordinary mechanical performance, without requiring additional fasteners. Our range of LOCTITE® products offer lower adherent thickness, letting you take advantage of the stiffness properties of composites and provides a separation of dissimilar materials.

A low viscosity system is needed for high temperature wet lay-up composite construction or repairs. With more than 50 years experience, Henkel’s catalogue of LOCTITE® laminate and wet lay-up resin solutions allow wet lamination as well as out-of-autoclave curing processes to be employed. Since they cure very fast under heat, they provide an optimal adhering surface for subsequent painting and coating.

For specialty aircraft construction repairs, Henkel offers materials such as surfacing films that provide a barrier for dissimilar materials, decrease surface preparation time, and provide protection of structural fibers. Laminated films composed of a surfacing film and a conductive metal foil protect the composite structure from damage caused by lightning strikes. With our LOCTITE® portfolio, you can be sure to get the technically most advanced aerospace surface finishing solutions.
