Abstract

A repair laminate for the quick repair of lightweight panels used particularly in aircraft construction comprised of a lightweight core 2, e.g., in the form of a possibly pressed honeycomb structure, and two outer laminates 3,4, which repair laminate is comprised of a solid cured or thermoplastic layer of synthetic material 13 bonded on one side to a hot-melt adhesive 15 and optionally on the other side to a decorative liner-layer. The synthetic material layer 13 may advantageously be a glass-fabric reinforced phenol aldehyde resin and the liner-laminate may be a dyed polyvinyl fluoride film. For the repair, an area 6 of the damaged lining laminates 3,4 and the core material below them is removed from the damaged section 5, and replacement core material is inserted into the space of the removed core areas and optionally the removed lining laminate areas; the panel surface at the damaged lining laminates 3,4 is ground off and repair laminate blanks 11 are glued over the areas of the damaged spots by being ironed onto the ground panel surface, whereby the blanks 11 laterally overlap the remote lining laminate areas 6.
