A literature survey on existing commercial adhesives suggested for very low temperature application demonstrated the superiority of the nylon-epoxy adhesives. A series of most promising existing adhesives was selected and evaluated more completely at very low temperature, again demonstrating the superiority of the nylon-epoxy systems.
Development work was aimed at adhesive systems applicable to field application and included filler and expansivity studies, metal surface preparations, and composite adhesive studies. Three adhesives were developed which demonstrate an excellent coverage of the program's target objectives. Extensive data are presented for these three developed adhesive systems.
