Equipment and techniques for rapid bonding of compositesRapid adhesive bonding concepts have been developed at NASA Langley which employ induction heating of thermoplastic composite matrices directly along the bond line and/or adherends without heating the entire structure, the supports, and the fixtures of the bonding assembly. Short term thermal cycling and water boil exposures have shown encouraging environmental stability for these rapid bonds. These bonding techniques have been extended to continuous seam bonding of metallic and composite panels with promising results for the bonding of both like and unlike adherends; the portability of the apparatus suggests that field repairs of damaged structures are possible.
